Notes
1. Total harmonic distortion is measured in a bandwidth of 22 Hz to 22 kHz, using an 11th-order low-pass filter. When
distortion is measured using a lower order low-pass filter a significantly higher value will be found, due to the
switching frequency outside the audio band.
2. Output power measured across the loudspeaker load.
3. Vripple = Vripple(max) = 2 V (p-p); fi = 100 Hz; Rs = 0 Ω.
4. Vripple = Vripple(max) = 2 V (p-p); fi = 1 kHz; Rs = 0 Ω.
5. B = 22 Hz to 22 kHz; Rs = 0 Ω.
6. B = 22 Hz to 22 kHz; Rs = 10 kΩ.
7. B = 22 Hz to 22 kHz; independent of Rs.
8. Vi = Vi(max) = 1 V (RMS).
