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. 5.0 3 12 Figure 2a. Driving CMOS
