Original question:

DAC7750: DAC7750 in Daisy-chain operation

DAC7750: A new device for daisy chain.

Part Number: DAC7750
Other Parts Discussed in Thread: DAC8775, DAC8771

Hi team,

DAC7750 can't daisy chain in the datasheet, so I'm looking for a new device that can daisy chain.
Do you have any recommended devices for 4 - 20mA?

Sincerely.
Kengo.

    Kengo,

    Instead of using a daisy chain, I would consider using a device with multiple channels, and a single SPI interface. One possible device to use the DAC8775. This device has four channels that can be used as either voltage output or current output. 

    If that's too many channels, I believe that the single channel DAC8771 can be used in a daisy chain configuration.
