ZSSC3123AA1C Description

The ZSSC3123 is a CMOS integrated circuit for accurate capaci-tance-to-digital conversion and sensor-specific correction ofcapacitive sensor signals. Digital compensation of sensor offset,sensitivity, and temperature drift is accomplished via an internaldigital signal processor running a correction algorithm with cali-bration coefficients stored in a non-volatile EEPROM.The ZSSC3123 is configurable for capacitive sensors with capaci-tances up to 260pF and a sensitivity of 125aF/LSB to 1pF/LSBdepending on resolution, speed, and range settings. It is com-patible with both single capacitive sensors (both terminals must beaccessible) and differential capacitive sensors. Measured andcorrected sensor values can be output as I2C, SPI, pulse densitymodulation (PDM), or alarms.The I2C interface can be used for a simple PC-controlled cali-bration procedure to program a set of calibration coefficients intoan on-chip EEPROM. The calibrated ZSSC3123 and a specificsensor are mated digitally: fast, precise, and without the costoverhead of trimming by external devices or laser.
