ADS8675: Wrong output from ADC

Part Number: ADS8675


I'm trying to read the output of the ADC & using variable power supply. The ADC output shows the multiple of 2 of applied input voltage.

For e.g if I'm giving 5V then ADC output shows 10V. 


  • Hi Rameez,

    This issue is mostly related to your digital timing, there is one bit was shifted. Can you please provide a timing captured with an analog oscilloscope for just one cycle including CONVST, SCLK,SDI and SDO? Also, please use a precision DC signal generator as an analog input signal to the ADC. 

    Best regards,
