霍尔效应集成电路、霍尔IC、低工作电压&低功耗、CMOS 工艺、MT1422A、MT1422AT

•CMOS process Bi-polar switchMicropower Hall Sensors Micropower consumption for battery powered applications High sampling frequency: 2K/s for high speed application Operation down to 2.2V Super high sensitivity :BOP=-10GS,BRP=10GS(Typical) Chopper stabilized amplifier Push-pull output.

•Description The MT1422Bi-polar switch micropowerHall effect sensor IC is fabricated from mixed signal CMOS technology .It incorporates advanced chopper-stabilization techniques to provide and stable magnetic switch points. Internal Sleep/awake logic and push pull output saving power consumption, high sampling frequency and low power design balance the contradiction between the high speed application and battery power supply.

•低工作电压&低功耗系列:此系列产品工作电压范围为2.2V-5V。利用IC的休眠与唤醒功能,达到降低功耗的目的。客户可根据实际应用的需要,选择不同的采样频率,以满足便携式产品的设计要求。
