DAC37J84

I'm using SPI to interface with DAC37J84 and I'm pretty new and I just couldn't seem to find it's default 7 bit device address?

Could someone point it out to me?

Thank you,

John

    Hi John

    Unlike some other interfaces (I2C for example) the SPI interface protocol doesn't have a 'device address'. The 7 bit address shown in Figures 58 and 59 of the datasheet identifies which register within the device will be written to or read from.

    The device itself is selected by asserting the SDENB input low at the beginning of the transaction. If there are multiple devices in the system they may be able to share the SCLK, SDIO and SDO signals, but they should have individual SDENB signals so they can be independently configured.

    Best regards,

    Jim B
