APPLICATION INFORMATION
BENEFITS OF THE LMC7221 TINY COMPARATOR
Size
The small footprint of the 5-Pin SOT-23 packaged Tiny Comparator, (0.120 x 0.118 inches, 3.05 x 3.00 mm)
saves space on printed circuit boards, and enable the design of smaller electronic products. Because they are
easier to carry, many customers prefer smaller and lighter products.
Height
The height (0.056 inches, 1.43 mm) of the Tiny Comparator makes it possible to use it in PCMCIA type III cards.
Simplified Board Layout
The Tiny Comparator can simplify board layout in several ways. First, by placing a comparator where
comparators are needed, instead of routing signals to a dual or quad device, long pc traces may be avoided.
By using multiple Tiny Comparators instead of duals or quads, complex signal routing and possibly crosstalk can
be reduced.
Low Supply Current
The typical 7 μA supply current of the LMC7221 extends battery life in portable applications, and may allow the
reduction of the size of batteries in some applications.
Wide Voltage Range
The LMC7221 is characterized at 15V, 5V and 2.7V. Performance data is provided at these popular voltages.
This wide voltage range makes the LMC7221 a good choice for devices where the voltage may vary over the life
of the batteries.
Digital Outputs Representing Signal Level
Comparators provide a high or low digital output depending on the voltage levels of the (+) and () inputs. This
makes comparators useful for interfacing analog signals to microprocessors and other digital circuits. The
LMC7221 can be thought of as a one-bit a/d converter.
Open Drain Output
The open drain output is like the open collector output of a logic gate. This makes the LMC7221 very useful for
mixed voltage systems.

Driving LEDs (Light Emitting Diodes)
With a 5 volt power supply, the LMC7221's output sinking current can drive small, high efficiency LEDs for
indicator and test point circuits. The small size of the Tiny package makes it easy to find space to add this
feature to even compact designs.
Input range to Beyond Rail to Rail
The input common mode range of the LMC7221 is slightly larger than the actual power supply range. This wide
input range means that the comparator can be used to sense signals close to the power supply rails. This wide
input range can make design easier by eliminating voltage dividers, amplifiers, and other front end circuits
previously used to match signals to the limited input range of earlier comparators. This is useful to power supply
monitoring circuits which need to sense their own power supply, and compare it to a reference voltage which is
close to the power supply voltage. The wide input range can also be useful for sensing the voltage drop across a
current sense resistor for battery chargers.
Zero Crossing Detector
Since the LMC7221's common mode input range extends below ground even when powered by a single positive
supply, it can be used with large input resistors as a zero crossing detector.
Low Input Currents and High Input Impedance
These characteristics allow the LMC7221 to be used to sense high impedance signals from sensors. They also
make it possible to use the LMC7221 in timing circuits built with large value resistors. This can reduce the power
dissipation of timing circuits. For very long timing circuits, using high value resistors can reduce the size and cost
of large value capacitors for the same R-C time constant.
Direct Sensor Interfacing
The wide input voltage range and high impedance of the LMC7221 may make it possible to directly interface to a
sensor without the use of amplifiers or bias circuits. In circuits with sensors which can produce outputs in the
tens to hundreds of millivolts, the LMC7221 can compare the sensor signal with an appropriately small reference
voltage. This may be done close to ground or the positive supply rail. Direct sensor interfacing may eliminate the
need for an amplifier for the sensor signal. Eliminating the amplifier can save cost, space, and design time.
LOW VOLTAGE OPERATION
Comparators are the common devices by which analog signals interface with digital circuits. The LMC7221 has
been designed to operate at supply voltages of 2.7V without sacrificing performance to meet the demands of 3V
digital systems.
At supply voltages of 2.7V, the common-mode voltage range extends 200 mV (ensured) below the negative
supply. This feature, in addition to the comparator being able to sense signals near the positive rail, is extremely
useful in low voltage applications.
Figure 16. Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages
Produces No Phase Inversion at the Output
At V+= 2.7V propagation delays are tPLH =4μs and tPHL =4μs with overdrives of 100 mV.

OPEN DRAIN OUTPUT
Output Stage
Figure 17. Output Stage
Figure 17 shows the difference between push-pull output and open drain output.
Push pull outputs will have a conventional high or low digital output, the same as a logic gate. Low will be the
negative supply rail (usually ground) and high will be the positive supply rail.
This is useful if the chips you are interfacing to run on the same supply voltage as the comparator. An example
would be an all +5V system.
Open drain outputs will only pull low—for the high output they depend on an external pull-up resistor. This can
pull up to a voltage higher or lower than the comparator supply voltage. This voltage can be as high as 15V. This
makes the open drain parts useful in mixed voltage systems. An example would be where the comparator runs at
5V and the logic circuits are at 3.3V. The pull-up resistor would go to the 3.3V supply.
Open drain outputs are the CMOS equivalent of open collector outputs.
OUTPUT SHORT CIRCUIT CURRENT
The LMC7221 has short circuit protection of 40 mA. However, it is not designed to withstand continuous short
circuits, transient voltage or current spikes, or shorts to any voltage beyond the supplies. A resistor in series with
the output should reduce the effect of shorts. For outputs which send signals off PC boards additional protection
devices, such as diodes to the supply rails, and varistors may be used.
INPUT PROTECTION
If input signals are likely to exceed the common mode range of the LMC7221, or it is likely that signals may be
present when power is off, damage to the LMC7221 may occur. Large value (100 kΩto MΩ) input resistors may
reduce the likelihood of damage by limiting the input currents. Since the LMC7221 has very low input leakage
currents, the effect on accuracy will be small. Additional protection may require the use of diodes, as shown in
Figure 18. Note that diode leakage current may affect accuracy during normal operation.
The R-C time constant of RIN and the diode capacitance may also slow response time.

LAYOUT CONSIDERATIONS
The LMC7221 is not an especially fast comparator, so high speed design practices are not required. The
LMC7221 is capable of operating with very high impedance inputs, so precautions should be taken to reduce
noise pickup with high impedance (100 kΩand greater) designs and in electrically noisy environments.
Keeping high value resistors close to the LMC7221 and minimizing the size of the input nodes is a good practice.
With multilayer designs, try to avoid long loops which could act as inductors (coils). Sensors which are not close
to the comparator may need twisted pair or shielded connections to reduce noise.
PUSH-PULL OUTPUTS, DUAL VERSIONS
The LMC7211 is a comparator similar to the LMC7221, but with push-pull outputs which can source current.
The performance of the LMC7221 is available in a dual device. Please see the LMC6772 datasheet. For a dual
device with push-pull outputs, please see the LMC6762 datasheet.
