Preliminary speciﬁcation

4

× 13 W single-ended power ampliﬁers

TDA8511J

Mode select switch

To avoid switch-on plops, it is advised to keep the amplifier

in the mute mode during >100 ms (charging of the input

capacitors at pins 1, 3, 15 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.
