Audio Amplifier Using TDA2050 32 Watt

Published

Introduction: Audio Amplifier Using TDA2050 32 Watt

Audio amplifier using TDA2050 IC max output of 32Watt

Step 1: Components List

2xLed
2x1K Resistors
2x22k Resistors
2x1000uF Capacitor
1x2 Ohm Resistor
1x0.47uf Cap
1x20K Potentiometer
1xTDA2050
1xBridge Rectifier

Step 2: Power Supply

The circuit uses a dual power supply to build the power supply use a 12V 5Amp transformer which gives a output of +12 And -12 Volt

Step 3: TDA2050

The IC gives a maximum power of 32Watt at 4ohm use a heatsink for the IC it gets very hot while in opration

Step 4: Circuit Diagram

Use circuit diagram to build the circuit you can also build this circuit on breadboard

Step 5: Stereo Use

For stereo application you can build a same copy of this circuit for the other channel

Step 6: OUTPUT

use a box enclosed speaker at output it gives a better bass output

Step 7: Sound Test Video

Step 8: Building the Circuit on Zero PCB

For a good connection than breadboard we can build this circuit on Zero PCB

    Check for any shorts.if its ok try adding capacitors to the power supply

    The ori version of TDA2050 has been discont...on 2012..Right now only the clone of TDA2050 on the market...This clone version 25W only..The ic protection not guaranteed 100% work.3A max...nomore 32W TDA2050 now...

    For the price...on my country...TDA2040 $12.50 .... TDA2050 clone only $7.45..

    TDA2040 more stable on low voltage .

    hello sir, can you please tell to me what is the cost of TDA2050 ic ? thank for the reading.......
