4x15Watt 12volt power audio amplifier
While I would have liked a 4 channel chip with about 20 Watt per channel, the local parts store didn't have any yet, so I opted for two TA8215AH stereo chips, selected by their low price in this particular store....
miniature audio amplifier
The amplifier is based on an integrated circuit TDA2822M. With this circuit, an amplifier can be built with up to 2 W. This much power circuit is able to supply only at peak times; continuous excitation would not be able...
TDA2030AL-TA5-T 18W Hi-Fi Audio Power Amplifier And 35W Driver
The TDA2549 is a complete intermediate frequency (IF) circuit that includes automatic frequency control (AFC), automatic gain control (AGC), demodulation, and video preamplification capabilities for multistandard television receivers. It can process both positively and negatively modulated video signals in color...
Mini-stereo
This circuit is constructed using two integrated circuits: the MC1458 dual operational amplifier, configured as a preamplifier, and the LM378 dual 4-watt amplifier. The gain of the preamplifier is determined by the resistor ratios R3/R1 for one channel and R4/R2...
40W/8ohms Audio Amplifier
Using the TB2922HQ audio power IC can be designed a very simple and high efficiency power audio amplifier electronic project. TB2922HQ is 2ch BTL audio amplifier for TV or home audio applications. It includes and the pure complementary P-ch and...
845 20W A1 class monotriode amplifier
This project is finalized, that means it is no longer experimental. This amplifier, although limited in output power (20W), has been designed to give the best listening pleasure. No compromise has been made during components choice: the 845 output triode...
Simple Hybrid Audio Amplifier Circuit
Here is an amplifier circuit based on the BUZ11, which can be replaced by an IRFZ34N, and an ECC83 can be used instead of the ECC88. In this case, the anode voltage should be reduced slightly to 155 V. The...
Schematic Audio Power Amplifier with IC TDA2612 Schematic Diagram
This amplifier circuit is based on the IC TDA2612 produced by Siemens. The minimum voltage required for this circuit is 10 volts, while the maximum voltage is 35 volts DC. The power output is 25 watts with a 4-ohm impedance....
PC audio amplifier 12Watt
The circuit utilizes the TDA2030, a monolithic integrated circuit housed in a Pentawatt package, designed for use as a low-frequency class AB amplifier. It typically delivers 14W of output power (with a distortion factor of 0.5%) at 14V with a...
