CD6283 Stereo Amplifier Circuit Diagram

CD6283/A6283 is Dual dual-channel Medium Power Audio Amplifier. The CD6283 is a dual-channel audio amplifier IC widely used in low-power audio amplification applications. It is a bridge amplifier with built-in thermal shutdown and low distortion output, making it ideal for stereo systems, small speaker amplifiers, and battery-powered audio devices. It operates in a bridge-tied load (BTL) configuration, which means it can deliver higher output power compared to a single-ended amplifier.

he CD6283 works as a power amplifier that boosts weak audio signals from sources like microphones, radios, and MP3 players to drive loudspeakers efficiently.
