cLite™ Low Voltage Capacitive Sensor Signal Conditioner
ZSSC3122
cLite™ Low Voltage Capacitive Sensor Signal Conditioner
Brief Description
The ZSSC3122 cLite™ 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 correction algorithm with calibration coefficients stored in a non-volatile EEPROM.
The ZSSC3122 is configurable for capacitive sensors with capacitances up to 10pF and a sensitivity of 125aF/LSB.
