I have a customer looking for a low cost, precision current source. He wants a SPI interface and current up to 30mA. Output voltage could range up to 16V. His application does not require very high accuracy (1-2% is probably fine). The AD5737 is a close fit using the 0-24 mA output range. Can I parallel 2 of the outputs to get greater current drive? If so, what is the easiest, safe way to do this?
Any other suggestions. He has already considered CN0151.
Apologies for the delay, I didnt get an alert on this one.
Paralleling Outputs directly should be fine, and the user could scale the gain register so that the full scale DAC value is 30mA
