(1)

(2)

A 33-

µH inductor was placed in series with the load resistor to emulate a small speaker for efficiency measurements.

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.
