1. CI was Shorted for any Common-Mode input voltage measurement .
2. A 33-mH 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.
