(1) C
I
was shorted for any common-mode input voltage measurement. All other measurements were taken with a 1- µ F
C
I
(unless otherwise noted).
(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.
