LM239 - Low-power quad voltage comparators

General Description

This family of devices consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM339A, LM239A, and LM139A.

Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages.

Key Features

  • Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V.
  • Very low supply current (1.1 mA) independent of supply voltage.
  • Low input bias current: 25 nA typ.
  • Low input offset current: ±5 nA typ.
  • Low input offset voltage: ±1 mV typ.
  • Input common-mode voltage range includes ground.
  • Low output saturation voltage: 250 mV typ; (ISINK = 4 mA).
  • Differential input voltage range equal to the sup.
