ZSSC3230 Datasheet (Renesas) - Capacitive Sensor Signal Conditioner

ZSSC3230, Capacitive Sensor Signal Conditioner

The ZSSC3230 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 correctio
