AD5700 logic signal isolation

There is no specification in the datasheet for RXD / CD – what current can
these outputs drive? We want to isolate these signals and now we must select
optocouplers according to the current capability of these outputs (not
interested in using iCoupler).

 

Depending on what supply value you are using: If you are using 3.3V, CD can
typically drive a load current of up to 3.4mA. With a supply voltage of 2V, CD
can drive a load current of up to 1.4mA. The other digital outputs should have
similar performance.
