TEST SET-UP FOR GRAPHS
(1) All measurements were taken with a 1- µ F C
I
(unless otherwise noted.)
(2) A 33- µ H 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.
(4) All THD + N graphs are taken with outputs out of phase (unless otherwise noted). All data is taken on left channel.
(5) All data is taken on the WCSP package unless otherwise noted.
