●Description
The Universal Standard LM393 / LM339 / LM2903 /
LM2901 family monolithic ICs integrate two / four
independent comparator circuits on a single chip and
feature high gain, low power consumption, and an
operating voltage range between 2[V] and 36[V]
(single power supply).
●Features
1) Operating temperature range
Commercial Grade LM339/393 family : 0[℃] to + 70[℃]
Extended Industrial Grade LM2903/2901 family : -40[℃] to +125[℃]
2) Open collector output stage
3) Single / dual power supply compatible
4) Low supply current
0.4[mA] typ.（LM2903/393 family）
1.1[mA] typ.（LM2901/339 family）
5) Low input-bias current: 25[nA] typ.
6) Low input offset current: 5[nA] typ.
7) Common-mode input voltage range includes ground
8) Differential input voltage is possible to apply the absolute maximum ratings±36[V].
9) Low output saturation voltage
10) TTL, MOS, CMOS compatible output
