DAC8568: How one microcontroller with SPI interface can communicate with multiple slave devices

Edward Herniak

Part Number: DAC8568


Please advise how one microcontroller with SPI interface can communicate with multiple slave devices ( 8) such as.DAC8568. The DAC8568 does not have Chip Select option and I am not too sure if I can use the SYNC pin as a CS.

    Hi Edward,

    Welcome to E2E and thank you for your query. You can use the /SYNC pin as the chip select. Please make sure the pin is pulled-up when inactive. You should also use separate /LDAC signals if you don't want to update all DAC's together.

    Hope I have answered your question.
