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.
