8 Parameter Measurement Information

All parameters are measured according to the conditions described in the Specifications section.

1. All measurements were taken with a 1-μF CI (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 kΩ 4.7 nF) is used on each output for the data sheet graphs.
