MT9711：Magnetic current/linear Hall chip - programmable current detection chip
MagnTek's MT9711 series products are a single-chip integrated programmable Hall effect linear sensor chip. It can be widely used in precise current detection or position detection. Each MT9711 consists of a highly sensitive Hall element, a low noise small signal high gain amplifier, a clamp circuit, an overcurrent protection output stage, and a high bandwidth dynamic compensation circuit. MT9711 outputs an analog voltage signal proportional to the applied magnetic flux density. Customers can flexibly configure sensitivity and calibrate static (zero magnetic field) output voltage by programming on the output pins to optimize the performance of the final application. Sensitivity can be adjusted within the range of 0.5~6.5mV/Gs through programming. The chip integrates a high-precision bandgap reference power supply, and its static output voltage and sensitivity vary with the variation of the power supply.
