Small stereo amplifier for computer with TDA7025


Small stereo amplifier for computer with TDA7025

Small stereo amplifier,low power, less devices, IC TDA7025 is the main equipment. 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.
