I am attempting to use this amp in unity gain. I am using the standard topolagy from the application notes (Figure 73). Measuring each output single endedly the magnitude is correct but they are in phase as is noted by the near zero measurement with a differential probe.
I am sure this is a stupid problem, I'm just learning this stuff. I appreciate all your help.
Usually when the outputs are in phase the amplifier is turned off or disabled. Have you verified the voltages on the Vs+, Vs-, and PD pins?
Power is correctly applied. There appears to be some loading I am unaware of. There were two series resistors inline with the both outputs, removing those and measuring across the outputs differetially gives the expected result. Something is apparently loading it funny on the other side of those.
