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.
