IAGNOSTIC OUTPUT
Special care must be taken in the PCB layout to separate
pin 4 from pins 1, 2, 16 and 17 to minimize the crosstalk
between the CLIP output and the inputs.
M
ODE 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 1, 2, 16 and 17). The circuit in
Fig.7 slowly ramps-up the voltage at the mode select
switch pin when switching on and results in fast muting
when switching off.
