ACS72981KLR - High-Precision Linear Hall-Effect-Based Current Sensor

Download the ACS72981KLR datasheet PDF. This datasheet also covers the ACS72981LLR variant, as both devices belong to the same high-precision linear hall-effect-based current sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

TheAllegro™ACS72981 family of current sensor ICs provides economical and precise solutions forAC or DC current sensing.

A 250 kHz bandwidth makes it ideal for motor control, load detection and management, power supply and DC-to-DC converter control, and inverter control.

Key Features

  • AEC-Q100 automotive qualification.
  • High-bandwidth 250 kHz analog output.
  • Less than 2 μs output response time.
  • 3.3 V and 5 V supply operation.
  • Ultralow power loss: 200 μΩ internal conductor resistance.
  • Industry-leading noise performance and increased bandwidth through proprietary amplifier and filter design techniques.
  • Greatly improved total output error through digitally programmed and compensated gain and offset over the full opera.
