1 / 10 page 1/10 s WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES FOR ALL DEVICES : +2V TO +36V OR ±1V TO ±18V s VERY LOW SUPPLY CURRENT (1.1mA) INDEPENDENT OF SUPPLY VOLTAGE (1.4mW/comparator at +5V) s LOW INPUT BIAS CURRENT : 25nA TYP s LOW INPUT OFFSET CURRENT : ±5nA TYP s LOW INPUT OFFSET VOLTAGE : ±1mV TYP s INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND s LOW OUTPUT SATURATION VOLTAGE : 250mV TYP; (Io = 4mA) s DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE s TTL, DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS DESCRIPTION These devices consist of four independent preci- sion 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 sin- gle power supply aver a wide range of voltages. Operation from split power supplies is also possi- ble. These comparators also have a unique character- istic in that the input common-mode voltage range includes ground even though operated from a sin- gle power supply voltage.
