AH810S Datasheet | Alfa Electronics

Hall Current Sensor 1.Product Introduction AH810S is a single chip programmable Hall effect linear sensor produced using advanced BCD technology. It includes a high sensitivity Hall sensor, high-precision Hall temperature pensation unit, Hall signal preamplifier, oscillator, dynamic offset elimination circuit, and amplifier output module. It can provide customers with more effective AC/DC current detection solutions and is widely used in munication, industrial, and consumer electronic devices. AH810S adopts overcurrent protection with 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 value of 2.5V. The internally integrated dynamic imbalance elimination circuit ensures that the sensitivity of the IC is not affected by external pressure and IC packaging stress. The output voltage of AH810S is proportional to the applied magnetic field strength, and customers can program on the power pin to adjust the chip sensitivity and static (zero field) output voltage, thereby improving product performance in the final application. AH810S has a static output voltage adjustable range of 2.5V ± 0.2V or 50% VCC, and an output sensitivity adjustable range of 1.8~30m V/Gs. 2.
