LM2903B Datasheet Low-power Dual Voltage Comparator

Manufacturer: STMicroelectronics

Overview: SO8 MiniSO8 TSSOP8 DFN8 2 x 2 wettable flanks Maturity status link LM2903B LM2903B Datasheet Low-power dual voltage.

General Description

The LM2903B consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages.

It is fully specified at 5 V and 36 V supply voltage operation, however operation from dual power supplies is also possible.

The B-grade version of the LM2903 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.

Key Features

  • Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V.
  • Very low supply current 0.5 mA typ. , essentially independent of supply voltage.
  • Low input bias current: 20 nA typ.
  • Low input offset current: ±5 nA typ.
  • Input common-mode voltage range includes negative rail.
  • Low output saturation voltage: 250 mV typ. (Iout = 4 mA).
  • TTL, DTL, ECL, MOS, CMOS compatible outputs.
  • Automotive qualification Applica.
