4 Channel Amplifier For Sound Card TDA2040

PC sound cards with multiple line outputs are commonplace than left and right channel for classical stereo reproduction. The described TDA2040 amplifier is designed especially for sound cards with four 2 + 1 + 1 output channels even those who have only a standard stereo signal, the amplifier described is complemented by simple custom ones

Amplifier 2.1 with TDA7377

Small amplifier TDA7377 of 15W + 15W + 30W in 4 ohms At the request of our followers, we have developed an amplifier with the following characteristics: The TDA7377 is the main component. It has 4 outputs that can deliver a power of 15W each. we distribute them as follows: First, we have 2 outputs

20W Stereo Amplifier With TDA2003 Tone Control

Many times we have been asked about an amplifier that can be powered with the computer source to amplify this. We have also seen the need for an amplifier that can be transportable everywhere and that provides an acceptable power service. Thinking about filling these expectations, we present a 20W stereo amplifier (10W per channel)

STK4241 STK4201 STK4221 STK4211 STK4231 Amplifier Circuit

The amplifier uses a hybrid two-channel IC STK4241-II manufactured by SANYO. Immediately, it is worth noting that the pinout of the STK4241 is compatible with such chips as the STK4201V-series (THD = 0.08%) and the STK4141-series (THD = 0.02%).
