DAC8775: DAC8775EVM - Accuracy vs Load

Part Number: DAC8775

Hello team,

 

Please find customer issue below:

**************************************************************************

 

I'm testing the board and I find that the accuracy depends on the load you put on the current loop. I must be doing something wrong.

This is the configuration I am using:

Measured results:

Code 152Dà

Shortcircuit -20.000mA

160ohms -19.890mA

470 ohms -19.681mA

As you can see, the result is different depending on the load.  Could you please help?

Thanks and regards, Jose
