NOTES:
1. Unless otherwise noted, C
2. To closely reproduce a real application case, all measurements are performed using the following loads:
3. For Efficiency measurements, the optional 30 kHz filter is used. An RC low-pass filter is selected with
Audio Input
input high pass filter is set to 10 Hz. Input capacitors are shorted for CMRR measurements.
Very low DCR 15 mH inductors (50 mW) have been used for the following graphs. Thus, the electrical load
measurements are performed on the resistor (8 W or 4 W) in differential mode.
(100 W, 47 nF) on each PWM output.

= 8 W means Load = 15 mH + 8 W + 15 mH
= 4 W means Load = 15 mH + 4 W + 15 mH
