LM139,A LM239,A-LM339,A LOW POWER QUAD VOLTAGE COMPARATORS WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES FOR ALL DEVICES : +2V TO +36V OR ±1V TO ±18V VERY LOW SUPPLY CURRENT (1.1mA) INDEPENDENT OF SUPPLY VOLTAGE (1.4mW/comparator at +5V) LOW INPUT BIAS CURRENT : 25nA TYP LOW INPUT OFFSET CURRENT : ±5nA TYP LOW INPUT OFFSET VOLTAGE : ±1mV TYP INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND LOW OUTPUT SATURATION VOLTAGE : 250mV TYP. (IO = 4mA) DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE TTL, DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS
DESCRIPTION These devices consist of four independentprecision voltage comparators with an offset voltage specifications as low as 2mV max for LM339A, LM239A and LM139A. All these comparators were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.
