TEST AND APPLICATION INFORMATION
Fig.7 Application circuit diagram.
Special care must be taken in the PCB-layout to separate pin 9 from the pins 10, 11 13 and 14 to minimize the crosstalk between the clip output and
the inputs.
To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during a period of
150 ms (charging the input capacitors at pins
10, 11, 13 and 14).
