50W Audio Power Amplifier with IC TDA1514A

Here is circuit audio amplifiers for car, which use it only number Transistor Circuit of IC, simple Circuit (and Top Popula)

Use TDA1514A transistor at low cost. It best Idea Circuit.

It’s receive a handful of additional external device in comparison to the generic diagram. Remember that there’s a simple HF filter on input signal. This IC supports mute and stand-by modes. I have not built this one, so I have get no suggestions concerning practical construction.

Supply Voltage = +/- 30V
Ur = 0-1V : Stand by
= 2-4.5V : Mute
= 6-7V : Play
