I have built this nice little tone controll unit with TDA1524. And now i vonder...
In the datasheet it says MAX input is 45mA @ 12V, and I'm using a 12V 250mA power suply. And my question is do i have to put a 267 ohms (12/0,045=266,666...) resistor in the middle of the suply pin (no. 3) and the power suply?
Heres the datasheet **broken link removed**
I'm also using an active lopass filter in the same power suply.
This may be a stupid question... but as i have said many times: I'm still a newb...
