LM393AD

P1-P3P4-P6P7-P9P10-P12P13-P13
January 2005 Revision 2 1/13
■ Wide single supply voltage range or dual
supplies : +2V to +36V or ±1V to ±18V
■ Very low supply current (0.4mA)
independent of supply voltage (1mW/
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 two independent low
voltage comparators designed specifically to
operate from a single 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.
