Notes:
(1) C
I
was Shorted for any Common-Mode input voltage measurement
(2) A 33-µH inductor was placed in series with the load resistor to emulate a small speaker for efficiency measurements.
(3) The 30-kHz low-pass filter is required even if the analyzer has a low-pass filter. An RC filter (100 W, 47 nF) is used on
each output for the data sheet graphs.
