TDA2005 Amplifier Circuit

| 2024/03/16

TDA2005 is a classic integrated circuit that achieves great things with low voltage. You can use it as a stereo or bridge depending on its location. It does not hesitate to protect itself in high temperatures and short circuit situations. In this study, we did a sweaty bridge connection study with him. Although it is…

Class A Headphone Amplifier 12V 5V

| 2024/03/14

The circuit is a two-stage amplifier with the output transistor operating in linear A mode with a quiescent current of approximately 180 mA. The entire amplifier consists of OOS circuit (elements C5, R5, R6). The resistances of resistors R5 and R6 determine the gain of the node. The output transistor must be mounted on a…

200W Amplifier Low High Bass Control TIP3055 TIP2955

| 2024/03/14

Output transistors in the 200W Amplifier circuit are TIP2955 and TIP3055. Working voltage is 2X42V DC symmetrical (2X30V AC). Power supply rectifier, filter, fuses, amplifier and low high bass control layer are on a single PCB. TL084 Op amp is used for the low high bass circuit, you can make the selection with the switch…

200W 500W Amplifier Powerful Bass Clear Sound

| 2023/10/18

I implemented the “200watt 300watt 400watt 500watt Amplifier Circuit” project that I shared years ago. Actually, I wanted to do it when I shared it, but quiescent current adjustment, measurements etc. I don’t like it 🙂 But after receiving occasional feedback about this amplifier for a long time, I wanted to try it. Since the…

8-OHM 100W RMS Amplifier 2SC5200

| 2023/10/18

A more stable, stable version of the 100 Watt Mono Amplifier known as ZENER in Colombia. It can deliver 100W power with an 8 Ohm speaker and can also be used with a 4 Ohm speaker. Its noise is very low, and it does not make an explosion sound when opened. Even though I use…
