Four precision independent comparators comprise the CMP04. Performance highlights include a very low offset voltage, low
5.0
output saturation voltage, and high gain in a single-supply design. The input voltage range includes ground for single-

requiring minimal power consumption. Maximum logic inter- face flexibility is offered by the open-collector TTL output. Figure 2a. Driving CMOS
