General Description

The ZSSC3123 is a CMOS integrated circuit for accurate capacitance-to-digital conversion and sensor-specific correction of capacitive sensor signals.

Digital pensation of sensor offset, sensitivity, and temperature drift is acplished via an internal digital signal processor running a correction algorithm with calibration coefficients stored in a non-volatile EEPROM.

The ZSSC3123 is configurable for capacitive sensors with capacitances up to 260pF and a sensitivity of 125aF/LSB to 1pF/LSB depending on resolution, speed, and range settings.

Key Features

  • Maximum target input capacitance: 260pF.
  • Sampling rates as fast as 0.7ms at 8-bit resolution; 1.6ms at 10-bit; 5.0ms at 12-bit; 18.5ms at 14-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.
