A. CI is shorted for any common-mode input voltage measurement.
B. A 33-μH inductor is placed in series with the load resistor to emulate a small speaker for efficiency measurements.
C. 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.
