![]() The IC has low crossover distortion, low quiescent current and is available in 16 pin power DIP package. On the printed circuit board, utilize an 8-pin IC socket for TDA2822M so that you can simply take away the IC throughout troubleshooting.TDA2822 is a monolithic integrated audio amplifier circuit that can be configured in stereo mode or bridge mode (BTL). Fix VR1 & VR2 potentiometers on the front board of the box intended for controlling the volume of left and right, respectively. After connecting the circuit, surround it in an appropriate box. TDA2822 Amplifier Circuit In Bridge Mode Stereo Amplifier Circuit with PCB LayoutĪ PCB layout and its components layout of the stereo amplifier circuit using TDA2822M is shown in the below figure. ![]() Here, C12 Capacitor is used to filter the power supply. The Branches like the R6, C10, and R5, C8 are intended for progressing higher frequency stability and stopping oscillations. The inverting i/p of these amplifiers are connected to GND with the help of capacitor branches like C9, C11. The non-inverting input of the next built-in amplifier is given to GND terminal. ![]() The input of the audio is given to the noninverting input (pin1) of the primary built-in amplifier. The TDA2822 amplifier output power can be improved by using it in this mode using the bridge arrangement and it is shown in below figure. Here, capacitor C7 is the power supply filter capacitor. The 4.7-ohm resistor and 0.1uF capacitor branch linked across speakers which are intended for progressing high-frequency strength and stopping oscillations. The outputs are fixed to the related speakers using capacitors like C1 & C2 correspondingly. ![]() The left and right amplified outputs are available at pins 6 &11 of the IC. The pin1 of these built-in amplifiers are connected to GND terminal with separate C5&C6 (1000uF) capacitors. Amplifier Circuit in Stereo Mode using TDA2822 The input of the left channel is given to the pin1 that is the noninverting input of the first built-in amplifier phase and the input of the right channel given to pin16 that is the noninverting input of the second built-in amplifier. TDA2822 IC integrated into stereo mode is shown in below figure. The pin configuration of TDA2822 IC is shown below.TDA2822 IC consist of 8-pins such as Pin Configuration of TDA2822 IC ![]()
