Hall Current Sensor - AH810S

AH810S is a monolithic programmable Hall-effect linear sensor manufactured using advanced BCD technology. It integrates a high-sensitivity Hall sensor, high-precision Hall temperature compensation unit, Hall signal pre-amplifier, oscillator, dynamic offset cancellation circuit, and amplifier output module, providing customers with a more effective AC/DC current detection solution, widely applicable to communication, industrial, and consumer electronic devices.

AH810S adopts overcurrent protection, high-bandwidth dynamic offset cancellation technology. In the absence of a magnetic field, the static output is a fixed 2.5V. The integrated dynamic offset cancellation circuit makes the IC's sensitivity unaffected by external pressure and IC package stress.

The output voltage of AH810S is proportional to the applied magnetic field strength. Users can program the sensitivity and static (zero-field) output voltage via the power supply pin to improve product performance in applications.

The static output voltage of AH810S is adjustable in the range of 2.5V±0.2V, and the output sensitivity is adjustable from 1.8 to 30mV/Gs.
