12VOLT RUNNING AMPLIFIER FOR MP4 MP3 PLAYER TDA2030 SCHEMATIC CIRCUIT DIAGRAM

I had to do a simple high-quality mono amplifier circuit that would work with 12volt batteries at the request of our brother. TDA2030 was a good choice.

We don’t know that mp3 / mp4 players are quite common constantly evolving with a wide range of audio outputs that can be upgraded to a complete sound system to be used as the source of the player in the simplest and cheaper than the simplest of a Chinese flash drive in the non-SD card used in models from the circuit board circuit on the circuit of the mp3 player feed With the LM317 added 1.5volt regulator.

I made my integrated work very easy to install with a few simple passive components to prepare the PCB troublesome I have prepared the PCB circuit of the single-feed application from the TDA2030 datasheet file that we will use with a 12-volt battery.

The result was quite good results in the 4-ohm loudspeaker 14watt power according to the information can be used with 12v battery, we can not get full efficiency but still enough and clean sound received a simple filter added to the input 12volt 12Volt output from a coil computer PSU power supply circuit I used to remove the coil I removed

PCB File .lay extension Sprint-Layout 5.0 you can open the program if you do not use the program for free only for monitoring and printing the Sprint-Layout-Viewer program.

The TDA2030 is a monolithic integrated circuit in the Pentawatt® package, intended for use as a low-frequency class-AB amplifier. Typically it provides 14 W output power (d = 0.5%) at 14 V/4 Ω. At ±14 V or 28 V, the guaranteed output power is 12 W on a 4 Ω load and 8 W on an 8 Ω (DIN45500).
