12bits-35KSps ULP SAR ADC

CT22406 is a 12-bit 35 kS/s Analog to Digital converter designed to deliver best in class performances in term of power consumption.

It is implemented employing SAR architecture.

A measurement Front-End section, to be customized according to the customer specifications, converts and adapt to the ADC range Voltage, Current and Temperature Sensors outputs from different ranges.

The IP includes a trimmable internal high accuracy voltage reference generator.

With 65uA total current consumption the figure of merit of the ADC is 7 pJ/step.
