Single Differential Comparator - TL331

TL331 (ACTIVE)

Single Differential Comparator

 

Description

This device consists of a single voltage comparator that is designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible if the difference between the two supplies is 2 V to 36 V and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The output can be connected to other open-collector outputs to achieve wired-AND relationships.

Features

  • Single Supply or Dual Supplies
  • Wide Range of Supply Voltage, 2 V to 36 V
  • Low Supply-Current Drain Independent of Supply Voltage, 0.4 mA Typ
  • Low Input Bias Current, 25 nA Typ
  • Low Input Offset Voltage, 2 mV Typ
  • Common-Mode Input Voltage Range Includes Ground
  • Differential Input Voltage Range Equal to Maximum-Rated Supply Voltage, ±36 V
  • Low Output Saturation Voltage
  • Output Compatible With TTL, MOS, and CMOS
