TDA2030 battery supply?!?

[Rockste4dy]

Hi, i`m a total noob so don`t be to brutal, hehe

I came across this tda2030
Is it possible to run it on a 12v battery supply?

Well from the picture it shows an ac input with ground. This may mean that it is running with a +ve and -ve rails with respect to ground. Without seeing more circuit details it would be difficult to say.

Maybe, if the PCB allows.

You can see that a pair of 100k resistors hold the non inverting input at 50% of the supply voltage.
