ADS8887: supported SPI modes

Bart

Part Number: ADS8887

Hi team,

which SPI modes (0,1,2 or 3) are supported by ADS8887? We guess it's mode 0, but there's no exact info on this in the datasheet.

Thanks a lot.

Hello Bart,

You are correct; ADS8887 SPI mode is SPI-00. It launches the MSB on the falling edge of CONVST(3-wire) or DIN(4-wire), and launches the remaining data bits on the falling edge of SCLK. The host typically will capture data on the rising edge of SCLK.
