LM393 Datasheet Low-power Dual-voltage Comparators

Manufacturer: STMicroelectronics

Overview: LM193, LM293 LM393, LM393W Datasheet Low-power, dual-voltage comparators DFN8 2x2 MiniSO8 TSSOP8 SO8 Maturity status link LM193, LM293, LM393,.

General Description

The LM193, LM293, LM393 and LM393W devices consist of two independent low voltage comparators designed specifically to operate from a single supply over a wide range of voltages.

Operation from split power supplies is also possible.

These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

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 (0.45 mA) independent of supply voltage (1 mW/ comparator at 5 V).
  • Low input bias current: 20 nA typ.
  • Low input offset current: ±3 nA typ.
  • Low input offset voltage: ±1 mV typ.
  • Input common-mode voltage range includes ground.
  • Low output saturation voltage: 80 mV typ. (Isink = 4 mA).
  • Differential input voltage range equ.
