[1] Dynamic distortion detector active; pin CLIP is LOW.

[2] Frequency response externally fixed.

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

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

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

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

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

Vcommon ≤ 3.5 V (RMS); fi = 1 kHz; Rs = 45 kΩ. 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 pin CLIP from

pins IN1+, IN1−, IN2+ and IN2− to minimize the crosstalk between the CLIP output 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.
