CT22403 is a 14-bit 10 Ms/s Analog to Digital converter. It is implemented with SAR architecture and offline calibration.

With 15mA total current consumption the Figure of merit of the ADC is 300 fJ/step, that is at the state of the art for its frequency sampling range. The calibration time at maximum clockfrequency is less than 20 us.
