12-bit 1-channel up to 1.25MSPS SAR ADC

Overview

028TSMC_ADC_01 is a 12-bit 1-channel successive-approximation-register (SAR) analog to digital converter (ADC) with sample rates up to 1.25 MSPS.
The IP includes an analog multiplexer which choses one of 32 inputs to be driven into the ADC.
Block has a reference voltage buffer for the ADC.
The block operates directly from VDDIO/VDD33/VDD09 supplies.
Analog voltage references can be generated from internal buffer or supplied externally.
