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
 Layout customized for die-die bonding with sensor for lowcost,
high-density chip-on-board assembly
 Accuracy as high as ±0.25% FSO@ -20 to 125°C, 3V, 5V,
Vsupply ±10% (see data sheet section 1.3 for restrictions)
 Minimized calibration costs: no laser trimming, one-pass
calibration using a digital interface
 Excellent for low-power battery applications
 Two interface options
 I2C or SPI interface—easy connection to a microcontroller
 PDM outputs (Filtered Analog Ratiometric) for both
capacitance and temperature
