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 single­supply 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 inter­face flexibility is offered by the open-collector TTL output.

The input common-mode voltage or input signal voltage should not be allowed to go negative by more than 0.3 V. The upper end of the common-mode voltage range
is V+ – 1.5 V, but either or both inputs can go to 30 V without damage.

NOTES

1

Absolute maximum ratings apply to both DICE and packaged parts, unless

otherwise noted. Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress rating only; functional
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.

θJA is specified for worst-case mounting conditions, i.e., θJA is specified for device

soldered to printed circuit board for SOIC package.

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.
