ADC0401X 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.
ADC0401X converts an analog input signal to 12-bit digital output codes, providing an on-chip sample-and-hold control and power-down control. The input range is typically 0 V to 1.2 V. The 16-to-1 analog input mux selects one of the 16 analog input channels to be sampled and converted. The power consumption of ADC0401X in normal operation mode is 0.5 mW at 1 MS/s.
The ADC0401X operates with two input clocks: main operation clock (CLK) and sampling clock (SOC). The frequencies of CLK and SOC are 20 MHz with 50% duty cycle and 1 MHz with 30% duty cycle, respectively. ADC0401X is suitable for mobile application processor, battery checker, portable equipment, and low-power applications.
