Comparators
LM393MX,LM2903MX,LM339MX,LM2901MX
Description
The Universal Standard family LM393 / LM339 / LM2903 / LM2901 monolithic ICs integrate two / four independent
comparators on a single chip and feature high gain, low power consumption, and an operating voltage range from 2[V] to
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 +85[]
2) Open collector output
3) Single / dual power supply compatible
4) Low supply current
0.8[mA] typ.(LM2901/339 family)
0.4[mA] typ.(LM2903/393 family)
5) Low input-bias current: 25[nA] typ.
16) Low input-offset current: 5[nA] typ.
7) Input common-mode voltage range, including ground
8) Differential input voltage range equal to maximum rated supply voltage
9) Low output saturation voltage
10) TTL,MOS,CMOS compatible output
