Overview
cLite™ Low-Voltage Capacitive Sensor Signal Conditioner ZSSC3122 Datasheet Brief Description The ZSSC3122 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals.
Digital compensation of sensor offset, sensitivity, and temperature drift is accomplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM.
The ZSSC3122 is configurable for capacitive sensors with capacitances up to 10pF and a sensitivity of 125aF/LSB.
It is compatible with both single capacitive sensors (both terminals must be accessible) and differential capacitive sensors.
Measured and corrected sensor values can be output as I2C, SPI, PDM, or alarms.
The I2C interface can be used for a simple PC-controlled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM.
The calibrated ZSSC3122 and a specific sensor are mated digital...
