Notes

1. VP = ±25 V; fi = 1 kHz; Tamb = 25 °C; measured in Fig.10; unless otherwise specified.

2. 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.

3. Vripple = Vripple(max) = 2 V (p-p); Rs = 0 Ω.

4. B = 22 Hz to 22 kHz and independent of Rs.

5. VP = ±25 V; fi = 1 kHz; Tamb = 25 °C; measured in reference design in Fig.12; unless otherwise specified.
