DAC8775: CURRENT OUTPUT 0~1mA

H264ER

Part Number: DAC8775
Other Parts Discussed in Thread: DAC8750, DAC53701, DAC80501

I want use DAC8775 to output a 0~1mA current signal, and the load is a pt100 resistor which connected GND directly.  Can I use DAC8775 to implement it?

    Do you only need one channel? The DAC8775 might be overly complicated for this application.  Depending on your required resolution, you could consider using the DAC53701 as a high-side current source, or a device like the DAC8750 or DAC80501+V/I stage.

    Thanks,
