Hi,
the easiest way that you use a Jack connector with internal switch like this.
But iam not sure where is the Jack connector in your circuit. On the input (Vin) or on the output (before the speaker)?
Input is Vin, Battery is Vs, where i could find jack connector like that?
Hi,
You can find it for exaple in Farnell http://hu.farnell.com/lumberg/1503-09/socket-3-5mm-jack-r-a-stereo/dp/1243244
This is a great amplifier too:
Schematic shows you exactly how to wire a headphone jack switch into it.
What if i want to use this chip for a guitar amp can it deliver a good cuality sound
