Part Number: ADC128S022

Hello team,

 

Our customer observed the below phenomenon and could we share their schematic internally ?

 

Conversion results has variation by SCLK as following.

They input 6.00V to A/D converter and the ideal conversion result will be 67C.

 

SCLK                   Sampling frequency            Conversion results

3MHz                   93.75kHz                            68C

1.5MHz                 46.875kHz                          6A3

 

Please give your advice and let me share their schematic internally to review it.

Thank you and best regards,

Michiaki
