LM239 - Quad voltage comparator

General Description

The LM139 series consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0mV max for each comparator, which were designed specifically to operate from a single power supply over a wide range of voltages.

Key Features

  • SL00070.
  • Wide single supply voltage range 2.0VDC to 36VDC or dual.
  • Very low supply current drain (0.8mA) independent of supply.
  • Low input biasing current 25nA.
  • Low input offset current ±5nA and offset voltage.
  • Input common.
  • mode voltage range includes ground.
  • Differential input voltage range equal to the power supply voltage.
  • Low output 250mV at 4mA saturation voltage.
  • Output voltage compatible with TTL, DTL, ECL, M.

INTEGRATED CIRCUITS LM139/239/239A/339/339A/LM2901/MC 3302 Quad voltage comparator Product specification IC11 Data Handbook 1995 Nov 27 Philips Semiconductors Philips Semiconductors Product specification Quad voltage comparator LM139/239/239A/339/339A /LM2901/MC3302 DESCRIPTION The LM139 series consists of four independent precision voltage comparators, with an offset voltage specification as low as 2.0mV max for each comparator, which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.
