4 x 12 W single-ended car radio power ampliﬁer with

dynamic distortion detector and diagnostic interface

TDA8562Q

AC CHARACTERISTICS

VP = 14.4 V; RL = 4 Ω; f = 1kHz; Tamb = 25 °C; measured in Fig.6; unless otherwise speciﬁed.

Notes

1. The circuit is DC adjusted at VP = 6 to 18 V and AC operating at VP = 8.5 to 18 V.

2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2.

3. Output power is measured directly at the output pins of the IC.

4. Frequency response externally fixed.

5. Ripple rejection measured at the output with a source-impedance of 0

Ω, maximum ripple amplitude of 2 V (p-p) and

at a frequency of between 100 Hz and 10 kHz.

6. Noise measured in a bandwidth of 20 Hz to 20 kHz.

7. Noise output voltage independent of Rs (VI = 0 V).
