Hi!
The IC outputs the two sinus-signals without load (top picture) but there are waveform problems with a 10 Ohm load (bottom). Why does this happen?
Here the additonal data:
* PVDD internally measured: 23.6V without load, 23.2V with load (0.4V voltage drop because of power supply filters at full load).
* AGAIN register (0x55): 0x06 ... 20.8V output span.
* PBTL mode: switch resistance < 100 mOhm ... switch voltage drop should not be a problem.
What I am doing wrong?
Thanks and best regards,
Edwin
