The ll_adc2891s01_lnf28lp_7002 is a 3.3V/1.8V/1.0V triple supply-voltage 12-ch 12-bit analog-to-digital converter (ADC) that supports conversion rate (FS) up to 4MS/s, designed in 28nm CMOS process. It consists of a 12-to-1 analog input MUX, a Cyclic type monolithic ADC, a clock generator, internal 5% and 95% voltage generator of reference voltage (EVREF) for calibration, a decoder for HTOL(high temperature operating life) test and level-shifters for low-voltage digital interface.
