How the CD6283 Stereo Amplifier Circuit Works

The audio signal is applied to the input pins of the CD6283 IC. The IC amplifies the input signal through its two internal amplifier channels and sends the amplified signals to the corresponding outputs.

Channel 1 uses the input and output pins associated with the first amplifier, while Channel 2 handles the second audio channel. The two outputs are connected to the speakers to reproduce the amplified stereo audio signal.

The feedback resistors are used to set the voltage gain of the amplifier. The input coupling capacitors block unwanted DC components from the audio source, while the bypass capacitors help improve circuit stability and frequency response.

CD6283 Circuit Component Functions

Feedback Resistors – R1 and R2

R1 and R2 are feedback resistors used to set the voltage gain of the amplifier. In this example, 560Ω resistors are used, giving a voltage gain of approximately 45dB according to the provided circuit information.

Input Capacitors – C1 and C2

C1 and C2 are input coupling capacitors. Their purpose is to block DC components from the audio input signal while allowing the AC audio signal to pass into the amplifier.

The example uses 1µF capacitors.

Bypass Capacitors – C3 and C4

C3 and C4 are bypass capacitors connected to the amplifier channels. They help improve the stability and frequency response of the circuit.

The example uses 100µF capacitors.

Power Supply Capacitor – C5

C5 is connected across the power supply to help reduce unwanted ripple and noise on the supply voltage. A 470µF capacitor is used in the example circuit.

Speakers – SP1 and SP2

SP1 and SP2 are the two speakers connected to the amplifier outputs. The example uses 8Ω speakers and specifies an output power of approximately 4.6W per channel at 12V.

Mute Switch – SW1

SW1 is used to control the mute function of the amplifier. When the mute control is activated, the audio output is muted. When the mute function is released, normal audio output is restored.

Power Supply – VCC
