Introduction

The AN4VB integrated current sensor (SOIC-16 package) uses compound semiconductor GaAs as its sensing core, with a built-in precision temperature compensation algorithm. It features high integration, high accuracy, high bandwidth, fast response, high linearity, and low temperature drift, providing a high-quality, efficient, and cost-effective solution for current sensing in industrial control, new energy, and automotive electronics applications. The sensor employs a differential Hall structure internally to effectively suppress external stray magnetic fields, offering strong immunity to interference and ensuring accurate measurements in complex magnetic noise environments. The device requires only low-side supply power, eliminating the inconvenience of dual high/low-voltage power supplies required by isolated op-amps. The product can be factory-calibrated to customer specifications, with no secondary programming or calibration required on the customer side.

Features
