ACSEVB-EX12 Evaluation Board

ACS71240 - Cost-Effective Shunt Alternative Hall-based Current Sensor

BaBare evaluation boards offer a method for evaluating Allegro current sensors in a lab environment. This document describes the use of the EX Package Bare Evaluation Board. This evaluation board (ACSEVB-EX12, TED-0004113) is intended for use with any EX packaged Allegro current sensor (EXB 12-contact QFN with wettable flank).
