ADC08D1520 data sheet states that: "If pin 52 (DRST_SEL: whether DCLK is reset using a single ended or differential signal) is floating or at logic high and pin 41(ECE:Extended Control Enable) is floating, this pin can be used to set the full-scale-range or can be used as an alternate Extended Control Mode enable pin. )".
How to set to make sure floating format on pin 52 and pin 41? We only set the pin as either 1 or 0. How does the data format matter?
With knowing this information, we will be able to guarantee ECE working mode of the adc chip.
