Hey!
In my project, I want to connect the DFR0768 mp3 component to a 3.3v or 5v linear voltage stabilizer. What is the maximum current that the speakers connected to the mp3 outputs will consume?
I mean, on what current should I choose the compound stabilizers so that they don't damage?
Attached is a picture from the spec:
I don't think that board can directly drive speakers...
But with 5V you can get 5V peak-to-peak out (theoretical maximum) which is about 1.75V RMS.
1.75V / 4 Ohms = 442mA. Double that for stereo (2 speakers) or for a bridge amplifier (twice the voltage), etc.
I will clarify my question: to the marked place (5 volts) I connect the mp3 component given to me which consumes over 20 ma, in addition there are 2 speakers coming out of this component and they are connected directly to the module because the module includes an internal amplifier. What is the current that the linear stabilizer will see and for which I should choose the stabilizer?
?Can someone please help me
