Description
The ZSSC3122 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals.
Features
- Maximum target input capacitance: 10pF.
- Sampling rates as fast as 0.7ms at 8-bit resolution; 1.6ms at 10-bit; 5.0ms at 12-bit; 18.5ms at14-bit.
- Digital compensation of sensor: piece-wise 1st and 2nd order sensor compensation or up to 3rd order single-region sensor compensation.
- Digital compensation of 1st and 2nd order temperature gain and offset drift.
- Internal temperature compensation reference (no external components).
- Programmable capacitance span and offset.
