and sorry if you will find this stupid but situation is quite serious.


As you saw from part III. I had ripple on output buffer. So I decided to use AD8436 without output buffer - only RMS. Since I was producing new PCB I also decided to suht down output buffer by not connecting OBUFV+ to 5V. Result is shocking: there is no output from RMS core.


Question is quite simple: If I am not using Output Buffer, should it be powered???


Best regards,
