LM2901 - Low-power quad voltage comparator

Description

This device consists of four independent precision voltage comparators, which are designed specifically to operate from a single supply over a wide range of voltages.

Operation from split power supplies is also possible.

Features

  • Wide single supply voltage range or dual supplies for all devices: +2 V to +36 V or ±1 V to ±18 V.
  • Very low supply current (1.1 mA) independent of supply voltage (1.4 mW/comparator at +5 V).
  • Low input bias current: 25 nA typ.
  • Low input offset current: ±5 nA typ. November 2023 This is information on a product in full production. DocID2468 Rev 10 1/20 www. st. com Contents Contents LM2901 1 Pin connection and schematic diagram.

LM2901 62 76623 4)1[ ZHWWDEOHIODQN Low-power quad voltage comparator Datasheet - production data • 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 Description This device consists of four independent precision voltage comparators, which are 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 the negative rail even though operated from a single power supply voltage.
