7.4.3 Single-Channel Mode (DES Mode)

The ADC12DL3200 can also be used as a single-channel ADC where the sampling rate is equal to two times the clock frequency (fS = 2 × fCLK) provided at the CLK+ and CLK– pins. This mode effectively interleaves the two ADC channels together to form a single-channel ADC at twice the sampling rate. This mode is chosen simply by setting DES_EN to 1. Either analog input, INA± or INB±, can serve as the input to the ADC. ADC trim settings are automatically adjusted based on the chosen input. The analog input can be selected using SINGLE_INPUT (see the input mux control register).
