The audio power amplifier is an important part of the sound of the sound system. The LM 3886 IC audio power amplifier with an audio power amplifier unit is very powerful and capable of producing 68 watts of 2  4 Ohm load power and is capable of delivering 38 W power with an 8 ohm load produce. With a well-placed sound of 20Hz-20kHz, playback is also included in the LM3886 audio power amplifier.

LM3886 Audio Power Amplifier Circuit

The LM3886 audio power amplifier is equipped with surge protection, which protects the output circuit from over voltage, under voltage, overload, konrsleting power supply, maximum runawaydan thermal temperature. The LM3886 audio power amplifier also has a noise cancellation system that keeps sound away from noise.

LM3886 Audio Power Amplifier Circuit Requirements:

• 68W cont. avg. output power into 4Ω at VCC = ± 28V
• 38W cont. avg. output power into 8Ω at VCC = ± 28V
