This ADC is a 1.2-V/0.75-V dual supply voltage 16-channel 12-bit Analog-to-Digital Converter (ADC) that supports conversion rate (FS) up to 1 MS/s, designed in 4-nm CMOS FinFET process. It consists of a 16-to-1 analog input mux, a Successive Approximation Register (SAR) type monolithic ADC, a clock generator, and level shifters for low-voltage digital interface.
