NXP Semiconductors TDA8566

2×40 W/2 Ω stereo BTL car radio power ampliﬁer

[1] Dynamic distortion detector active; pinCLIP is LOW.[2] Frequency response externally ﬁxed.[3] Vripple=V

ripple(max)= 2 V (p-p); Rs=0Ω.

[4] Noise measured in a bandwidth of 20Hz to 20 kHz.

[5] Common mode rejection ratio measured at the output (overRL) with both inputs tied together;

Vcommon≤3.5 V (RMS); fi= 100 Hzto 10 kHz; Rs=0Ω.

[6] Common mode rejection ratio measured at the output (overRL) with both inputs tied together;

Vcommon≤3.5 V (RMS); fi= 1 kHz; Rs=45kΩ. The mismatch of the input coupling capacitors is excluded.12. Application information

12.1 Diagnostic output

Special care must be taken in the PCB layout to separate pinCLIP from

pins IN1+, IN1−, IN2+ and IN2− to minimize the crosstalk between the CLIPoutput and

the inputs.

12.2 Mode select switch

To avoid switch-on plops, it is advisable to keep the ampliﬁer in the mute mode during

≥150 ms (charging of the input capacitors at pins IN1+, IN1−, IN2+ and IN2−). The circuit

in Figure 8 slowly ramps-up the voltage at the mode select switch pin when switching on

and results in fast muting when switching off.
