Bridge mode dual power amplifier:

This is the bridge mode dual power amplifier. Here we can use TDA2030 or TDA2050. This circuit diagram can make a maximum of 35 watts. Here needs a dual voltage. positive, negative, and ground voltage. minimum 10-0-10 voltage to 18-0-18 voltage can use. TDA2030 runs with a maximum 15-0-15 voltage, and TDA2050 runs with a maximum 22-0-22 voltage. but my claim is maximum 18-0-18 voltage for tda2050 and 15-0-15 for the tda2030.

A good voltage can make a good output of watts.

How to make an amplifier circuit:

How to make an amplifier circuit? This is a mini audio amplifier circuit diagram. It can make 30 watts in bridge mode using 15 volts. This diagram needs a single voltage, positive and negative. It’s a mono diagram. To make a stereo need a dual board is needed. Here, use the TDA2003 IC. The dual IC needs to be in bridge mode. The IC needs a headsink. And the voltage must be good to make the best watts. We can use 8 volts to 18 volts. and up to 3 amperes.

How to make an amplifier circuit

We can get many amplifier circuit diagrams. This circuit can be used in a 2.1 sound box. We can make a subwoofer amplifier using this diagram. To make a subwoofer, we need a low-pass filter circuit. To get the lowpass filter circuit, please visit here LOWPASS FILTER. We need this low-pass filter to make a bass amplifier for 2.1 audio. This low-pass filter makes the sound only bass. It’s also a pre-amplifier. We can use this circuit in any amplifier to make a subwoofer amplifier.
