Quad Low Power, Precision Comparator CMP04 FEATURES PIN CONNECTIONS High Gain: 200 V/mV Typ Single- or Dual-Supply Operation 14-Lead SOIC Input Voltage Range Includes Ground Low Power Consumption (1.5 mW/Comparator) Low Input Bias Current: 100 nA Max OUT 2 1 14 OUT 3 Low Input Offset Current: 10 nA Max OUT 1 2 13 Low Offset Voltage: 1 mV Max OUT 4 1 4 Low Output Saturation Voltage: 250 mV @ 4 mA V+ 3 12 GND Logic Output Compatible with TTL, DTL, ECL, MOS, IN 1– 4 11 IN 4+ and CMOS IN 1+ 5 10 IN 4– Directly Replaces LM139/LM239/LM339 Comparators IN 2– 6 2 3 9 IN 3+ IN 2+ 7 8 IN 3– CMP04 GENERAL DESCRIPTION TYPICAL INTERFACE
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-
