Q12. What is the SPI mode of operation of the AD4111/AD4112/AD4114/AD4115, what polarity do I need to consider?
The interface operates in SPI Mode 3 (CPOL=1, CPHA=1) wherein SCLK idles high, the falling edge of SCLK is the drive edge, and the rising edge of SCLK is the sample edge. Data is clocked out on the falling/drive edge and data is clocked in on the rising/sample edge.
