Fonctionnalités et applications

The LM2903D device consists of two independent low power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.

This comparator also has a unique characteristic: the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.


  • Wide single supply voltage range or dual Supplies +2 V to +36 V or ±1 V to ±18 V
  • Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at +5 V)
  • ow input bias current: 25 nA typ.
  • Low input offset current: ±5 nA typ.
  • Input common-mode voltage range includes negative rail
  • Low output saturation voltage: 250 mV typ. (IO = 4 mA)
  • Differential input voltage range equal to the supply voltage
  • TTL, DTL, ECL, MOS, CMOS compatible Outputs
