ACSEVB-EZ7 Evaluation Board

Low Resistance, High Power Density Current Sensor in QFN or Widebody SOIC-6 Package

Evaluation boards offer a method for quickly evaluating Allegro current sensors in a lab environment without needing a custom circuit board. This document describes the use of the EZ current sensor evaluation board.
