(1) C
I
was Shorted for any Common-Mode input voltage measurement.
(2) A 33- µ H 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 an internal low – pass filter. An RC low pass filter (100
Ω , 47 nF) is used on each output for the data sheet graphs.
