If you want will build a Small stereo amplifier project for computer. This projects is best for you. Before read detail of they we should read mono model on This is Super Small Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little.
This is Super Small and mini Power Amplifier BCL 1.2W by TDA7052. If you are seeking the circuit amplifies small-sized. I begs for to advise this circuit because tiny economize with the equipment is a little. And still can use force against large-sized get comfortably ( I has tried already ) besides it still is low voltage amplifier circuit that volts power supply very wide be about 1.5V arrive at 15V as well.It is tiny size and can adjust volume by VR1. Regard as IC TDA7052 be worthwhile very much. For you who want to try build this circuit. I has model PCB give a friend tests to see with. Request have fun the circuit amplifies miniature please.

Then you can apply to this our project. Small stereo amplifier with TDA7052
Small stereo amplifier circuit using TDA7052
The Small stereo amplifier circuit,low power, less devices, IC TDA7025 is the main part. Operation of the circuit, the signal split into left and right through the capacitor coupling of C1, C2 is a variable resistor VR1 adjusts the strength of the input signals to bridge amplifiers power suppliers IC1-. IC2, serves to amplify the signal up, drive out the speakers left – right.
Resistors R1, R2 set the input impedance to the circuit box,The capacitor C4, the current filter to smooth and C1 reduce noise, and high frequency, resulting from the power supply to ground. It helps to stabilize the circuit.
This circuit power supply: 6-volt battery or batteries, only 4 watts of output power up to 1.5 watts at 8-ohm speakers to the sound of small TV, radio, cassette player. It’s a light or sound. No one was banned. Only has a headphone jack or the phone becomes available.
How to build this small stereo amplifier circuit
We can build this projects with see the PCB layout in Figure 2 with Universal PCB form for saving time and moneny.
Parts you will needs
C1,C2_____10uF 25V Electrolytic Capacitors
R1,R2_____5.6K 0.5W resistors
VR1,VR2____4.7K or 5K potentiometer trimmer resistors
Speaker 8ohms 5 Watts
