 After the pure power amp is simply the volume of the amplifier, without preamplifier, audio input directly without any modification after pushing pronounce speaker amplified sound authentic, pure and natural. The amplifier board is to use two sound pretty classic ST's TDA2030 amplifier IC composed of pure power amp, a single power supply, single-supply input voltage AC 9V-15V, reasonable layout elements, strong power (15Wx2), almost no static noise , an excellent sense of hearing, fewer external components, easy to install, very suitable for conversion or installation of home audio system, widely used in a variety of speakers, most of the market 150 -200 computer speakers, are used TDA2030 amplifier IC production.

I. Circuit Description:

The power amplifier integrated circuit TDA2030 amplifier board is composed of the center, reasonable layout element, almost no static noise, high fidelity, low distortion, fewer external components, simple assembly, power 15W + 15W) and other characteristics, suitable for electronic enthusiasts and audiophiles DIY, student assembly.

 

D is the rectifier diode circuit, C11 for the filter capacitor, C12, C13 for the high-frequency decoupling capacitors; RP for the volume control potentiometer; IC1, IC2 is a two-channel amplifier IC; R1, R2, R3, C1 ( R7, R8, R9, C6) for the bias circuit amplifier IC input, as the circuit is a single power supply, amplifier IC input DC voltage is half the supply voltage circuit to work properly; R4, R5, C3 (R10 , R11, C8) form a negative feedback loop, change R4 (R10) of the feedback coefficient can be resized. C2 (C7) is the input coupling capacitor, C4 (C9) is the output coupling capacitor; when the circuit is connected with the inductive load speaker, R6, C5 (R12, C10) to ensure high frequency stability.
