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 de-
sign. 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 mini-
mal power consumption. Maximum logic interface flexibility is
offered by the open-collector TTL output.
