Hi Sharada, If all of the error reporting is disabled do you still see this drop to ~1/2 of the setpoint? If so, this is likely a symbol timing issue which may cause the incorrect data being latched into the DAC. The symbols are based on the duty cycle of the input waveform. The easiest way to identify the issue is to monitor DIN, ACKB, ERRB and the output (voltage across the load) on a single scope plot when this current drop occurs. Any timing issues should be visible in the DIN waveform. Can you provide this? Thanks, Garrett
