Overview
cLiteTM 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 PCcontrolled calibration procedure to program a set of calibration coefficients into an on-chip EEPROM.
The calibrated ZSSC3122 and a specific sensor are mated...
