ADS8588S: REGCAP1 and REGCAP2 coupled together

Part Number: ADS8588S

Tool/software:

Dear Experts,

We have designed a microcontroller card with ADS8588S on the board. We have recently learned that both the REGCAP1 and REGCAP2 were coupled together by mistake. I see the datasheet that both the pins are to be decoupled separately.  I would like to know if the ADC would work with the existing connection?

Regards,

Rajesh BN.

    Hi Rajesh,

    The ADS8588S will still work, however you may see some degradation in the performance of the chip.  If you have the chance to make hardware changes, I would ask you to follow the datasheet recommendation and bypass the two pins separately.
