IDT ZSSC3122
The ZSSC3122 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals. 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.| Part No. | ZSSC3122 |

DESCRIPTION
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. 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
