8 Parameter Measurement Information

All parameters are measured according to the conditions described in the Specifications. Figure 34 shows the

setup used for the typical characteristics of the test device.

(1)

(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

(100 Ω, 47 nF) is used on each output for the data sheet graphs.
