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).

●

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
