DIY audio amplifiers circuit diagram electronics projects and other related audio projects like : power amplifiers, audio systems, audio filters, vu meters, tone control, audio equalizers and more .
This 12 watts audio amplifier circuit audio amplifier electronic project is very simple and is based on TDA1020 integrated amplifier and few external components .
Using BA3812L equalizer circuit you can build is a five-point graphic equalizer circuit that has all the required functions integrated into one IC.
Main features of the BA3812L graphic equalizer circuit are: low distortion and low noise, wide operating power supply voltage range (3.5V to 16V), low current dissipation (5 mA), wide dynamic range (VOM = 2.1Vrms/VCC = 8V), built-in input and output buffer amplifiers.
Using Atmel AT73C240 stereo audio converter circuit IC with integrated power audio amplifier can be designed a simple audio amplifier for portable devices.
