Notes
1. VP = ±25 V; RL = 4 Ω; fi = 1 kHz; Tamb = 25 °C; measured in reference design in Figs 9 and 11; unless otherwise
specified.
2. Indirectly measured; based on Rds(on) measurement.
3. Total Harmonic Distortion (THD) is measured in a bandwidth of 22 Hz to 22 kHz. When distortion is measured using
a low-order low-pass filter a significantly higher value will be found, due to the switching frequency outside the audio
band.
4. Efficiency for power stage; output power measured across the loudspeaker load.
5. VP = ±25 V; RL = 8 Ω; fi = 1 kHz; Tamb = 25 °C; measured in reference design in Figs 9 and 11; unless otherwise
specified.
