16b 10Msps ADC

AD16BSAR10M40LP is a 16-bit Successive Approximation Analog-to- Digital Converter (ADC) made in 40nm technology at 3.6V down-to 1.6V analog supply.

The ADC is capable to operate up to 10MS/s achieving full 16bit linearity, with no missing code. An efficient and accurate in-built linearity Calibration Engine present inside the ADC removes mismatch of the DAC capacitors. The linearity calibration allows using smaller capacitor size in the capacitive DAC inside the ADC. This reduces ADC footprint and saves switching power. Access to read and write the Calibration codes allows quick reloading of the calibration codes without need to re-run the calibration again.

The ADC is equipped with Low Power mode for additional power saving.

The ADC is also supports a Low Noise mode with further improved SNR.

The ADC is capable of processing Differential and Single-Ended Inputs.
