AC CHARACTERISTICS

VP = 14.4 V; RL =4 Ω; f = 1 kHz; Tamb =25 °C; measured in Fig.7; unless otherwise speciﬁed.

Notes

1. Frequency response externally fixed.

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

3. B = 20 Hz to 20 kHz; Rs =0 Ω.

4. B = 20 Hz to 20 kHz; Rs =10kΩ.

5. B = 20 Hz to 20 kHz; independent of Rs.

6. PO = 16 W; Rs =10kΩ.

7. Vi =Vi(max) = 1 V (RMS).

8. Dynamic Distortion Detector (DDD) active, pin 9 is set to logic 0.
