1. The 1-µF input capacitors on IN+ and IN– were shorted for input common-mode voltage measurements.
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 an internal low-pass filter. An R-C low-pass filter (100 Ω, 47 nF) is used on each output for the data sheet graphs.
