Hi team,

Could you give me comment on following customer question?

Q1. Can the customer connect to the same SPI bus with ADS8689? Do you have any concerns about it?

Best regards,

    Hi Sasaki,

    You can use multiple SPI slaves in SPI bus provided your SPI master has different chip select signals for different slaves.

    You can share DATA, CLOCK and SDO between ADC and DAC, and have independent  CHIP SELECT for both devices. I don't see any issues f you follow these.

    Let me know if you need more info regarding this.

    Regards,

    AK
