Description:

Pure power amp is simply the volume of the amplifier, without preamplifier circuit, audio input directly promote the pronunciation without any modification after speaker amplified sound authentic, pure and natural. The amplifier board is pretty sound using two classic ST's TDA2030 amplifier IC composed of pure power amp, single power supply, input voltage single supply AC 9V-15V, rational component layout, 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.

Principle Description:
The power amplifier IC TDA2030 amplifier board is composed of the center, component layout is reasonable, almost no static noise, high fidelity, low distortion, fewer external components, assembly is simple, big power 15W + 15W), etc., suitable for electronic enthusiasts and audiophiles DIY, student assembly.


Circuit for rectifying diode D, C11 for the filter capacitor, C12, C13 for high frequency decoupling capacitors; RP for 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 supply, power amplifier IC when the input DC voltage to half the supply voltage circuit to work properly; R4, R5, C3 (R10 , R11, C8) form a negative feedback loop, change R4 (R10) can change the size of the feedback coefficients. C2 (C7) is the input coupling capacitor, C4 (C9) is the output coupling capacitor; when the circuit is connected with inductive load speaker, R6, C5 (R12, C10) ensures high frequency stability.

Performance Parameters:
Input voltage: AC9-15V or DC9-15V (DC input note to distinguish between sub-polar, AC input, regardless of polarity)
Output power: Po = 15W + 15W (RL = 4Ω)
Output impedance: 4-8 Ω
PCB Size: 66x56mm, thickness: 1.6mm, Material: FR-4
