TEST SET-UP FOR GRAPHS

(1)

All measurements were taken with a 1-

µF C

I (unless otherwise noted.)

(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 RC low-pass filter (1 k

Ω

4.7 nF) is used on each output for the data sheet graphs.
