      8 capacitance sensor inputs
      25 ms update rate, all 8 sensor inputs
      No external RC components required
      Automatic conversion sequencer
   On-chip automatic calibration logic
      Automatic compensation for environmental changes
      Automatic adaptive threshold and sensitivity levels
   Register map compatible with AD7143
   On-chip RAM to store calibration data
   I2C-compatible serial interface
   Separate VDRIVE level for serial interface
   Interrupt output
   16-lead, 4 mm × 4 mm LFCSP
   2.6 V to 3.3 V supply voltage
