Beijing Zhongke Yinhe core technology Co., Ltd. has launched resistance type and capacitance type signal conditioning chip. The chip has the functions of amplification, calibration and temperature compensation. Resistance signal conditioning chip is suitable for sensors with output sensitivity from 4MV / V to 60mV / V, and supports voltage bridge and current bridge excitation. Support 4-20mA and 0-5V full swing output. The capacitive signal conditioning chip can connect a group of variable capacitors or a single variable capacitor and a fixed reference capacitor pair. Then, through the internal C-V conversion circuit and 15bit ADC, the corresponding linear 15bit data is generated. Through the internal logic and EPROM, the span and offset of the data are adjusted to output a 16bit data corresponding to the full range range range of the variable capacitor.
