2 channel Hi-fi Amp using tda2030a











◆ PCB printed circuit board size: 88 * 73 * 1.6mm; refined overall height: 32mm.
◆ Output power: Speaker impedance 8Ω � 12V voltage output power of about 15Wx2.
◆ voltage range � 6 - � 22V
▲ circuit features:
[1] very few external components.
[2], output power, Po = 18W (RL = 4Ω).
[3] with ultra-small package (TO-220), can increase the packing density.
[4] turn impact is minimal.
[5] containing various protection circuits, so safe and reliable. The main protection circuit: short circuit protection, thermal protection, accidental open ground, reverse polarity (Vsmax = 12V) and load discharge voltage recoil and so on.
[6] TDA2030A � 6V maximum in the minimum voltage of � 22V to work in the � 19V, 8Ω impedance to the effective power output of 16W, THD ≤ 0.1%. No doubt, use it for computer power amplification part of the active speaker or a small amplifier appropriate.

use tda 2050 for better performance
better sounding than 2030 @ almost same price
also, rated 32w & can be powered +/- 20v
using same ckt as 2030.

my ganito palang thread
eto galing pang elab


AUDIO AMPLIFIER TDA2030 2 + 1 CHANNEL


This project is Power Audio Amplifier with TDA2030 2.1 Chanell – 3 x 18 Watts – Subwoofer – Complete With PCB suggestion and power supply.



This circuit is a complete application is 2.1 amp, two satellite speakers for TDA and one for the subwoofer, making the 2.1 system, widely used in commercial applications as an amplifier for computers, which may give an increased in its audio system with a stereo amplifier bass amplifier (subwoofer).

Description of the amplifier circuit with TDA 2030

The circuit is divided into 3 parts: power supply, amplifier, stereo amplifier and bass amplifier (subwoofer).


TDA2030 2.1 – Schematic of the power amplifier



Power supply circuit and pre low pass filter for the sub power supply

The power supply is of symmetric type, using a transformer, 110 or 220 with dual secondary 12 volts and 3A current. I recommend using a fuse and a switch before the transformer. B1 is a bridge rectifier least 100 volts / 4 A, an example that can be used is GBU606, the filtering circuit is formed of the capacitors C1, C2, C3 and C4, the electrolytes can have values ​​from 4700μF . The power supply for the op amp Highpass filter, is used three terminal integrated circuits 7812 and 7912.



Circuit of the amplifiers of satellite speakers

The left and right channels give exactly the same, let’s see how the left channel: LIN is the audio input jack, which is coupled by C20 to the pot volume adjustment, it is a double pot, and set the two channels simultaneously. R19/C22, helps to improve the signal of the treble. The capacitor C21 couples the signal to CI6 TDA2030, after amplified audio output is pin 4 of integrated. The resistor R7 and R9 are responsible for feedback, so by changing the value of R7 can increase or decrease the gain of the amplifier. R20 and C23 form the compensation network for the speakers.


Circuit pre and Amplifier Subwoofer

The signal comes from the subwoofer to the left and right channels by resistors R15 and R10 being decoupled by capacitor C12, is applied in the operational amplifier 1 IC4A NE5532, which forms a pre-amplifier to boost the signal by 6 times. Determined by R6/R8 resistor.

The components C9, C10 and R10 form a low pass filter in this case is calculated to 200Hz. After leaving IC4B the low frequency audio through the potentiometer P1 that makes the volume level, then forwarded to IC3 is what makes the subwoofer amplifier, the operating principle is the same as satellite amplifiers.



Suggested PCB for the circuit of the amplifier
