1 / 62 page  Datasheet ZSSC3123 cLiteTM Capacitive Sensor Signal Conditioner Nov 19, 2021 Page 1 © 2021 Renesas Electronics Description The ZSSC3123 is a CMOS integrated circuit for accurate capaci- tance-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 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/LSB depending on resolution, speed, and range settings. It is com- patible 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, pulse density modulation (PDM), or alarms. The I2C interface can be used for a simple PC-controlled cali- bration procedure to program a set of calibration coefficients into an on-chip EEPROM. The calibrated ZSSC3123 and a specific sensor are mated digitally: fast, precise, and without the cost overhead of trimming by external devices or laser. Available Support ZSSC3123 SSC Evaluation Kit available: SSC Evaluation Board, samples, software, documentation. Support for industrial mass calibration available. Quick circuit customization option for large production volumes.
