DESCRIPTION
The OPA348 series amplifiers are single supply, low-power,
CMOS op amps in micro packaging. Featuring an extended
bandwidth of 1MHz, and a supply current of 45µA, the
OPA348 series is useful for low-power applications on single
supplies of 2.1V to 5.5V.
Low supply current of 45µA, and an input bias current of
0.5pA, make the OPA348 series an optimal candidate for
low-power, high-impedance applications such as smoke de-
tectors and other sensors.
The OPA348 is available in the miniature SOT23-5 and
SO-8 packages. The OPA2348 is available in SOT23-8 and
SO-8 packages, and the OPA4348 is offered in space-saving
TSSOP-14 and SO-14 packages. The extended temperature
range of –40°C to +125°C over all supply voltages offers
additional design flexibility.

ESD damage can range from subtle performance degrada-

FIGURE 3. OPA348—No Phase Inversion with Inputs Greater
than the Power-Supply Voltage.
APPLICATIONS INFORMATION
OPA348 series op amps are unity-gain stable and suitable
for a wide range of general-purpose applications.
The OPA348 series features wide bandwidth and unity-gain
stability with rail-to-rail input and output for increased dynamic
range. Figure 1 shows the input and output waveforms for the
OPA348 in unity-gain configuration. Operation is from a single
+5V supply with a 100kΩ load connected to VS/2. The input is
a 5Vp-p sinusoid. Output voltage is approximately 4.98Vp-p.
Power-supply pins should be bypassed with 0.01µF ceramic
capacitors.
on the high end. Within the 200mV transition region PSRR,
CMRR, offset voltage, offset drift, and THD may be degraded
compared to operation outside this region.

OPERATING VOLTAGE
OPA348 series op amps are fully specified and tested from
+2.5V to +5.5V. However, supply voltage may range from
+2.1V to +5.5V. Parameters are tested over the specified
supply range—a unique feature of the OPA348 series. In
addition, all temperature specifications apply from –40°C to
+125°C. Most behavior remains virtually unchanged through-
out the full operating voltage range. Parameters that vary
significantly with operating voltages or temperature are shown
in the Typical Characteristics.
COMMON-MODE VOLTAGE RANGE
The input common-mode voltage range of the OPA348 series
extends 200mV beyond the supply rails. This is achieved
with a complementary input stage—an N-channel input differ-
ential pair in parallel with a P-channel differential pair. The
N-channel pair is active for input voltages close to the positive
rail, typically (V+) – 1.2V to 300mV above the positive supply,
while the P-channel pair is on for inputs from 300mV below the
negative supply to approximately (V+) – 1.4V. There is a small
transition region, typically (V+) – 1.4V to (V+) – 1.2V, in which
both pairs are on. This 200mV transition region, shown in
Figure 2, can vary ±300mV with process variation. Thus, the
transition region (both stages on) can range from (V+) – 1.7V
to (V+) – 1.5V on the low end, up to (V+) – 1.1V to (V+) – 0.9V
RAIL-TO-RAIL INPUT
The input common-mode range extends from (V–) – 0.2V to
(V+) + 0.2V. For normal operation, inputs should be limited to
this range. The absolute maximum input voltage is 500mV
beyond the supplies. Inputs greater than the input common-
mode range but less than the maximum input voltage, while not
valid, will not cause any damage to the op amp. Unlike some
other op amps, if input current is limited the inputs may go
beyond the power supplies without phase inversion, as shown
in Figure 3.

In unity-gain inverter configuration, phase margin can be
reduced by the reaction between the capacitance at the op
amp input, and the gain setting resistors, thus degrading
capacitive load drive. Best performance is achieved by using
small valued resistors. For example, when driving a 500pF
load, reducing the resistor values from 100kΩ to 5kΩ de-
creases overshoot from 55% to 13% (see the typical charac-
teristic “Small-Signal Overshoot vs. Load Capacitance”).
However, when large valued resistors cannot be avoided, a
small (4pF to 6pF) capacitor, CFB, can be inserted in the
feedback, as shown in Figure 6. This significantly reduces
overshoot by compensating the effect of capacitance, CIN,
which includes the amplifier's input capacitance and PC
board parasitic capacitance.
FIGURE 6. Improving Capacitive Load Drive.
Normally, input currents are 0.5pA. However, large inputs
(greater than 500mV beyond the supply rails) can cause
excessive current to flow in or out of the input pins. There-
fore, as well as keeping the input voltage below the maxi-
mum rating, it is also important to limit the input current to
less than 10mA. This is easily accomplished with an input
voltage resistor, as shown in Figure 4.

OVERLOAD
RAIL-TO-RAIL OUTPUT
A class AB output stage with common-source transistors is
used to achieve rail-to-rail output. This output stage is ca-
pable of driving 5kΩ loads connected to any potential be-
tween V+ and ground. For light resistive loads (> 100kΩ), the
output voltage can typically swing to within 18mV from supply
rail. With moderate resistive loads (10kΩ to 50kΩ), the output
voltage can typically swing to within 100mV of the supply
rails while maintaining high open-loop gain (see the typical
characteristic “Output Voltage Swing vs Output Current”).
CAPACITIVE LOAD AND STABILITY
The OPA348 in a unity-gain configuration can directly drive
up to 250pF pure capacitive load. Increasing the gain en-
hances the amplifier’s ability to drive greater capacitive loads
(see the typical characteristic “Small-Signal Overshoot vs
Capacitive Load”). In unity-gain configurations, capacitive
load drive can be improved by inserting a small (10Ω to 20Ω)
resistor, RS, in series with the output, as shown in Figure 5.
This significantly reduces ringing while maintaining DC per-
formance for purely capacitive loads. However, if there is a
resistive load in parallel with the capacitive load, a voltage
divider is created, introducing a Direct Current (DC) error at
the output and slightly reducing the output swing. The error
introduced is proportional to the ratio RS/RL, and is generally
negligible.

DRIVING A/D CONVERTERS
The OPA348 series op amps are optimized for driving
medium-speed sampling Analog-to-Digital Converters (ADCs).
The OPA348 op amps buffer the ADCs input capacitance
and resulting charge injection while providing signal gain.
The OPA348 in a basic noninverting configuration driving the
ADS7822, see Figure 7. The ADS7822 is a 12-bit,
micro
POWER sampling converter in the MSOP-8 package.
When used with the low-power, miniature packages of the
OPA348, the combination is ideal for space-limited, low-
power applications. In this configuration, an RC network at
the ADC’s input can be used to provide for anti-aliasing filter
and charge injection current.
The OPA348 in noninverting configuration driving ADS7822
limited, low-power applications. In this configuration, an RC
network at the ADC’s input can be used to provide for anti-
aliasing filter and charge injection current. See Figure 8 for
the OPA2348 driving an ADS7822 in a speech bandpass
filtered data acquisition system. This small, low-cost solution
provides the necessary amplification and signal conditioning
to interface directly with an electret microphone. This circuit
will operate with VS = 2.7V to 5V with less than 250µA typical
quiescent current.
