ZSC31050FAG1 IDT原装 差动传感器
发布时间： 2017/3/1 15:23:22 | 2018 次阅读
The ZSC31050 is a CMOS integrated circuit for amplification and sensor-specific correction of bridge sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift and non-linearity by a 16-bit RISC microcontroller running a correction algorithm. The ZSC31050 accommodates virtually any resistive bridge sensor (e.g., piezo-resistive and steel-membrane-base_d pressure sensors). In addition, the device can interface to a separate temperature sensor. The bi-directional digital interfaces (I2C, SPI, ZACwire™) can be used for a simple PC-controlled calibration procedure, encompassing writing and programming a set of calibration coefficients into an on-chip EEPROM. The ZSC31050 has been designed for industrial, medical and consumer applications and is specifically suited for most pressure sensors. It can also be used with force, torque, acceleration, angle, position and revolution sensors.
