May I use AD5754R and AD5752R for Daisy-Chain function of 6 channel DAC output?

Dear Sir:

                     May I use AD5754R and AD5752R for Daisy-Chain function of 6 channel DAC output? BTW, In daisy-chain mode, May I has been pull low for LDAC pin?

 

Best Regard

    Hi Jason,

    I see no problem in using the two parts in daisy chain mode to implement a 6 channel DAC output. Keep in mind on how the daisy chaining works. Please refer to the Daisy-Chain Operation section in the datasheet for detailed information on daisy-chaining SPI devices.

    When operating in daisy chain mode, all your devices are connected to a single SCLK, SYNC, and LDAC. Yes, you may but remember that when LDAC is tied permanently low, the addressed DAC register is updated on the rising edge of SYNC.

    If you have any other questions, please do not hesitate to ask.

    Regards,

    Mark
