Description
LM321/358/324 types consist of single/dual/quad
channel independent, high gain, internally frequency
compensated operational amplifiers which are
designed specifically to operate from a single power
supply over a wide range of voltages. They may also
be operated from split power supplies. The supply
current is basically independent of the supply
voltage over the recommended voltage range.
These devices are particularly useful in interface
circuits with digital systems and can be operated
from the single common 5VDC power supply. They
are also intended for transducer amplifiers, DC gain
blocks and many other conventional op amp circuits
which can benefit from the single power supply
capability.
In the linear mode, the input common-mode voltage
range includes ground and the output voltage can
also swing to both ground and power rail, even
though operated from a single power supply.
The LM321 is single channel version available in
5-pin SOT23 packages. The LM358 is dual channel
version available in 8-pin SOP and MSOP packages.
The LM324 is quad channel version available in
14-pin SOP and TSSOP packages.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input
current should be limited to less than 10mA.
Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many
amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces
connected to the leads.

1.2MHz, Low-Power 36V Op Amps
Pin Functions
-IN: Inverting Input of the Amplifier.
+IN: Non-Inverting Input of Amplifier.
OUT: Amplifier Output. The voltage range extends to
within mV of each supply rail.
V+ or +Vs: Positive Power Supply. Typically the voltage
is from 3V to 36V. Split supplies are possible as long
as the voltage between V+ and V– is between 3V and
36V. A bypass capacitor of 0.1μF as close to the part as
possible should be used between power supply pins or
between supply pins and ground.
V- or -Vs: Negative Power Supply. It is normally tied to
ground. It can also be tied to a voltage other than
ground as long as the voltage between V+ and V– is from
3V to 36V. If it is not connected to ground, bypass it
with a capacitor of 0.1μF as close to the part as
possible.
Operation
The LM321/358/324 output signal range extends beyond the negative and positive power supplies. The intput can even
extend all the way to the negative supply. The Class-AB control buffer and output bias stage uses a proprietary
compensation technique to take full advantage of the process technology to drive very high capacitive loads. This is
evident from the transient over shoot measurement plots in the Typical Performance Characteristics.
Applications Information
High Supply Voltage and Low Power Consumption
The LM321/358/324 of operational amplifiers can operate with power supply voltages from 3V to 36V. Each amplifier
draws only 100μA quiescent current. The low supply voltage capability and low supply current are ideal for portable
applications demanding HIGH CAPACITIVE LOAD DRIVING CAPABILITY and WIDE BANDWIDTH. The
LM321/358/324 is optimized for wide bandwidth low power applications. They have an industry leading high GBWP to
power ratio and are unity gain stable for 10nf CAPACITIVE load. When the load capacitance increases, the increased
capacitance at the output pushed the non-dominant pole to lower frequency in the open loop frequency response,
lowering the phase and gain margin. Higher gain configurations tend to have better capacitive drive capability than
lower gain configurations due to lower closed loop bandwidth and hence higher phase margin.
Low Input Referred Noise
The LM321/358/324 provides a low input referred noise density of 48nV/√Hz at 1kHz. The voltage noise will grow
slowly with the frequency in wideband range, and the input voltage noise is typically 10μVP-P at the frequency of 0.1Hz
to 10Hz.
Low Input Offset Voltage
The LM321/358/324 has a low offset voltage tolerance of 3mV maximum which is essential for precision applications.
The offset voltage is trimmed with a proprietary trim algorithm to ensure low offset voltage for precision signal
processing requirement.
Low Input Bias Current
The LM321/358/324 is a CMOS OPA family and features very low input bias current in pA range. The low input bias
current allows the amplifiers to be used in applications with high resistance sources. Care must be taken to minimize
PCB Surface Leakage. See below section on “PCB Surface Leakage” for more details.
PCB Surface Leakage

LM321/LM358/ LM324
1.2MHz, Low-Power 36V Op Amps
www.3peakic.com.cn Rev. B.01
In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be
considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity
conditions, a typical resistance between nearby traces is 1012Ω. A 5V difference would cause 5pA of current to flow,
which is greater than the LM321/358/324 OPA’s input bias current at +27°C (±1pA, typical). It is recommended to use
multi-layer PCB layout and route the OPA’s -IN and +IN signal under the PCB surface.
The effective way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard
ring is biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 1 for
Inverting Gain application.
1. For Non-Inverting Gain and Unity-Gain Buffer:
a) Connect the non-inverting pin (VIN+) to the input with a wire that does not touch the PCB surface.
b) Connect the guard ring to the inverting input pin (VIN–). This biases the guard ring to the Common Mode input voltage.
2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors):
a) Connect the guard ring to the non-inverting input pin (VIN+). This biases the guard ring to the same reference voltage as
the op-amp (e.g., VS/2 or ground).
b) Connect the inverting pin (VIN–) to the input with a wire that does not touch the PCB surface.

Figure 1
Ground Sensing and Rail to Rail Output
The LM321/358/324 has excellent output drive capability, delivering over 35mA of output drive current. The output
stage is a rail-to-rail topology that is capable of swinging to within 5mV of either rail. Since the inputs can go 100mV
beyond either rail, the op-amp can easily perform ‘True Ground Sensing’.
The maximum output current is a function of total supply voltage. As the supply voltage to the amplifier increases, the
output current capability also increases. Attention must be paid to keep the junction temperature of the IC below 150°C
when the output is in continuous short-circuit. The output of the amplifier has reverse-biased ESD diodes connected to
each supply. The output should not be forced more than 0.5V beyond either supply, otherwise current will flow through
these diodes.
ESD
The LM321/358/324 has reverse-biased ESD protection diodes on all inputs and output. Input and out pins cannot be
biased more than 200mV beyond either supply rail.
Feedback Components and Suppression of Ringing
Care should be taken to ensure that the pole formed by the feedback resistors and the parasitic capacitance at the
inverting input does not degrade stability. For example, in a gain of +2 configuration with gain and feedback resistors of
10k, a poorly designed circuit board layout with parasitic capacitance of 5pF (part +PC board) at the amplifier’s
inverting input will cause the amplifier to ring due to a pole formed at 1.2MHz. An additional capacitor of 5pF across the
feedback resistor as shown in Figure 2 will eliminate any ringing.
Careful layout is extremely important because low power signal conditioning applications demand high-impedance
circuits. The layout should also minimize stray capacitance at the OPA’s inputs. However some stray capacitance may
be unavoidable and it may be necessary to add a 2pF to 10pF capacitor across the feedback resistor. Select the
smallest capacitor value that ensures stability.

Driving Large Capacitive Load
The LM321/358/324 of OPA is designed to drive large capacitive loads. Refer to Typical Performance Characteristics
for “Phase Margin vs. Load Capacitance”. As always, larger load capacitance decreases overall phase margin in a
feedback system where internal frequency compensation is utilized. As the load capacitance increases, the feedback
loop’s phase margin decreases, and the closed-loop bandwidth is reduced. This produces gain peaking in the
frequency response, with overshoot and ringing in output step response. The unity-gain buffer (G = +1V/V) is the most
sensitive to large capacitive loads.
When driving large capacitive loads with the LM321/358/324 (e.g., > 200 pF when G = +1V/V), a small series resistor
at the output (RISO in Figure 3) improves the feedback loop’s phase margin and stability by making the output load
resistive at higher frequencies.

Power Supply Layout and Bypass
The LM321/358/324 OPA’s power supply pin should have a local bypass capacitor (i.e., 0.01μF to 0.1μF) within 2mm
for good high frequency performance. It can also use a bulk capacitor (i.e., 1μF or larger) within 100mm to provide
large, slow currents. This bulk capacitor can be shared with other analog parts.
Ground layout improves performance by decreasing the amount of stray capacitance and noise at the OPA’s inputs
and outputs. To decrease stray capacitance, minimize PC board lengths and resistor leads, and place external
components as close to the op amps’ pins as possible.
Proper Board Layout
To ensure optimum performance at the PCB level, care must be taken in the design of the board layout. To avoid
leakage currents, the surface of the board should be kept clean and free of moisture. Coating the surface creates a
barrier to moisture accumulation and helps reduce parasitic resistance on the board.
Keeping supply traces short and properly bypassing the power supplies minimizes power supply disturbances due to
output current variation, such as when driving an ac signal into a heavy load. Bypass capacitors should be connected
as closely as possible to the device supply pins. Stray capacitances are a concern at the outputs and the inputs of the
amplifier. It is recommended that signal traces be kept at least 5mm from supply lines to minimize coupling.
A variation in temperature across the PCB can cause a mismatch in the Seebeck voltages at solder joints and other
points where dissimilar metals are in contact, resulting in thermal voltage errors. To minimize these thermocouple
effects, orient resistors so heat sources warm both ends equally. Input signal paths should contain matching numbers
11
LM321/LM358/ LM324
1.2MHz, Low-Power 36V Op Amps
www.3peakic.com.cn Rev. B.01
and types of components, where possible to match the number and type of thermocouple junctions. For example,
dummy components such as zero value resistors can be used to match real resistors in the opposite input path.
Matching components should be located in close proximity and should be oriented in the same manner. Ensure leads
are of equal length so that thermal conduction is in equilibrium. Keep heat sources on the PCB as far away from
amplifier input circuitry as is practical.
The use of a ground plane is highly recommended. A ground plane reduces EMI noise and also helps to maintain a
constant temperature across the circuit board.
Instrumentation Amplifier
The LM321/358/324 OPA is well suited for conditioning sensor signals in battery-powered applications. Figure 4
shows a two op-amp instrumentation amplifier, using the LM321/358/324 OPA.
The circuit works well for applications requiring rejection of Common Mode noise at higher gains. The reference
voltage (VREF) is supplied by a low-impedance source. In single voltage supply applications, VREF is typically VS/2.

Two-Pole Micro-power Sallen-Key Low-Pass Filter
Figure 5 shows a micro-power two-pole Sallen-Key Low-Pass Filter with 400Hz cut-off frequency. For best results,
the filter’s cut-off frequency should be 8 to 10 times lower than the OPA’s crossover frequency. Additional OPA’s
phase margin shift can be avoided if the OPA’s bandwidth-to-signal ratio is greater than 8. The design equations for
the 2-pole Sallen-Key low-pass filter are given below with component values selected to set a 400Hz low-pass filter
