ZSSC3122 - Low-Voltage Capacitive Sensor Signal Conditioner
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 correctio
ZSSC3122 Features
