Hall Current Sensor 1. Product Introduction AH910 is a high-performance Hall-effect current sensor that can measure alternating current (AC) or direct current (DC) more effectively. It can be widely used in industrial, consumer and munication equipment. AH910 series internal integration of a high precision, low noise linear Hall circuit and a low impedance main current loop wire, when the sampling current flows through the main current loop, the magnetic field generated in the Hall circuit induction of the corresponding electrical signal, through the signal processing circuit output voltage signal, so that the product output is strictly proportional to the measured current value. The linear Hall circuit is produced by advanced BCDMOS process, which includes high sensitivity Hall sensor, Hall signal pre-amplifier, high precision Hall temperature pensation unit, oscillator, dynamic offset elimination circuit and amplifier output module. In the absence of a magnetic field, the current sensor has a static output of 2.5V fixed voltage or 50%VCC. Under the condition of power supply voltage 5V, the static output of the sensor can change linearly with the magnetic field between 0.2 ~ 4.8V, and the linearity can reach 0.4%. The dynamic offset elimination circuit integrated in AH910 makes the sensitivity of the sensor not affected by external pressure and IC package stress. The AH910 is available in a SOP8 package with an operating temperature range of -40 to 150 ° C, which is Ro HS pliant. 2.
