St microelectronics LM339N quad bipolar voltage comp'
WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES FOR ALL DEVICES :
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
LOW OUTPUT SATURATION VOLTAGE :
DIFFERENTIAL INPUT VOLTAGE RANGE EQUAL TO THE SUPPLY VOLTAGE
TTL, DTL, ECL, MOS, CMOS COMPATIBLE OUTPUTS
These devices consist of four independent precision 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 aver 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.
