ACS37032 - High-Accuracy Current Sensor

This page provides the datasheet information for the ACS37032, a member of the ACS37030 High-Accuracy Current Sensor family.

Datasheet Summary

Description

The ACS37030/2 is a fully integrated current sensor IC that senses current flowing through the primary conductor.

Two signal paths are used: a Hall-effect element path to capture DC and low-frequency current information, and an inductive coil path to capture high-frequency current information.

Features

  • High operating bandwidth for fast control loops or where high-speed switching currents are monitored.
  • DC to 5 MHz bandwidth.
  • 40 ns typical response time.
  • High accuracy and low noise.
  • ±2% sensitivity error over temperature.
  • ±10 mV maximum offset voltage over temperature.
  • 50 mARMS input referred noise.
  • 3.3 V non-ratiometric supply operation.
  • Differential sensing immune to external magnetic fields.
  • VREF outpu.
