CD6283 Stereo Audio Amplifier Circuit
If you are looking for a simple and low-cost way to build a stereo audio amplifier, you might be interested in the 6283 IC pinout. The 6283 IC is a dual-channel audio power amplifier with built-in thermal shutdown protection and low popping noise at power on. It can deliver up to 4.6 W per channel at 12 V supply voltage and has a voltage gain of 45 dB. In this article, we will explain the 6283 IC pinout, its features, and how to use it in a circuit diagram.
What is the 6283 IC?
The 6283 IC is an audio power IC with built-in two channels developed for portable audio devices. It comes in a single inline package (SIP) with 12 pins. It has a low quiescent current of 7 mA and can operate with a supply voltage range of 6 V to 15 V. It also has a built-in thermal shutdown protection circuit that prevents the IC from overheating and damaging itself.
The 6283 IC has two input pins, two output pins, two feedback pins, two bypass pins, two ground pins, one Vcc pin, and one mute pin. The input pins are used to connect the audio signal sources, such as MP3 players, CD/DVD players, or radio tape players. The output pins are used to connect the speakers or headphones. The feedback pins are used to set the voltage gain of the amplifier by connecting resistors between them and the output pins. The bypass pins are used to connect capacitors to improve the stability and frequency response of the amplifier. The ground pins are used to connect the common ground of the circuit. The Vcc pin is used to connect the positive supply voltage of the circuit. The mute pin is used to control the output signal level by connecting a switch or a transistor between it and the ground.

6283 IC stereo audio amplifier Circuit diagram
In this circuit diagram, the following components are used:
- R1 and R2 are feedback resistors that set the voltage gain of the amplifier. They are chosen to be 560 ohms, which gives a voltage gain of about 45 dB.
- C1 and C2 are input coupling capacitors that block any DC component from the audio signal sources. They are chosen to be 1 uF, which gives a cutoff frequency of about 160 Hz.
- C3 and C4 are bypass capacitors that improve the stability and frequency response of the amplifier. They are chosen to be 100 uF, which gives a cutoff frequency of about 16 Hz.
- C5 is a power supply decoupling capacitor that reduces any ripple or noise from the supply voltage. It is chosen to be 470 uF, which gives a cutoff frequency of about 0.7 Hz.
- SP1 and SP2 are speakers or headphones that reproduce the amplified audio signals. They are chosen to be 8 ohms, which gives an output power of about 4.6 W per channel at 12 V supply voltage.
- SW1 is a mute switch that controls the output signal level by connecting or disconnecting the mute pin to the ground. When SW1 is closed, the output signal is muted. When SW1 is open, the output signal is normal.
- Vcc is the supply voltage source that powers the circuit. It can be any DC source between 6 V and 15 V. In this example, it is chosen to be 12 V.
