Quad Low Power,
Precision Comparator
FEATURES
High Gain: 200 V/mV Typ
Single- or Dual-Supply Operation
Input Voltage Range Includes Ground
Low Power Consumption (1.5 mW/Comparator)
Low Input Bias Current: 100 nA Max
Low Input Offset Current: 10 nA Max
Low Offset Voltage: 1 mV Max
Low Output Saturation Voltage: 250 mV @ 4 mA
Logic Output Compatible with TTL, DTL, ECL, MOS,
and CMOS
Directly Replaces LM139/LM239/LM339 Comparators
GENERAL DESCRIPTION
Four precision independent comparators comprise the CMP04.
Performance highlights include a very low offset voltage, low
output saturation voltage, and high gain in a single-supply
design. The input voltage range includes ground for single-
supply operation and V for split supplies. A low power
supply current of 2 mA, which is independent of supply voltage,
makes this the preferred comparator for precision applications
requiring minimal power consumption. Maximum logic inter-
face flexibility is offered by the open-collector TTL output.

operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the CMP04 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
