Lack of SPI slave select

Hi,

I was considering using several AD5410 instead of a complex AD5735 in my circuit but I've found out that AD5410 does not come with a SPI slave select. Is there another way to individually control each converter in a single SPI bus?

Thanks, Daniel

  • Hi Daniel,

    May I ask why you think so?

    the latch pin is Positive Edge Sensitive Latch similar to the SYNC pin, (form teh AD5735 DS) the addressed DAC output is updated on the rising edge of SYNC.

    The only different is that SYNC needs to be low during all the transmission and the latch only needs to be toggled at the end.

    Best Regards,

    Miguel
