Product Introduction
AH810 is a monolithic programmable Hall-effect linear sensor manufactured using advanced BCD process. 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 more effective AC/DC current detection solutions. It is widely applicable to communication, industrial, and consumer electronic devices.
AH810 adopts overcurrent protection, high-bandwidth dynamic offset cancellation technology. In the absence of a magnetic field, the static output can be selected as 50% VCC or a fixed 2.5V. The integrated dynamic offset cancellation circuit makes the IC's sensitivity immune to external pressure and IC package stress.
The output voltage of AH810 is proportional to the applied magnetic field strength. Users can program the sensitivity and quiescent (zero-field) output voltage via the power supply pin to improve product performance in applications.
The quiescent output voltage of AH810 is adjustable within 2.5V±0.2V or 50% VCC, and the output sensitivity is adjustable from 1.66 to 29.3 mV/Gs.
