I send 0x0000 as DAC Code. Then when I measure between Vout and ground, I see a value of about 1V. When I send FF, I see 3.3V. Shouldn't I see 0.3V and 2.5V in default mode? Or should I not take the...

View ArticleForum Post: RE: ADS8661: Unable to confirm if the ADC is properly functioning
Hi Fahad, Your SPI phase setting is incorrect. SDI and SDO should both be valid on the rising SCLK edge. Please set your controller to Mode 0 (CPOL=0, CPHA=0) and see if that clears up your issues.
