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

These devices consist of fourindependentprecision

voltage comparators with an offset voltage specifi-

cations 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 characteris-

tic in that the input common-mode voltage range

includes ground even thoughoperatedfrom a single

power supply voltage.
