LM3886 Gainclone 2x68 Watt Full Amplifier Project

Description: The LM3886 is an improved version of the LM3875. Key features of the LM3886 include a maximum output power of 68W RMS and 108W peak, with a total harmonic distortion (THD) of 0.03% at 60W.

The LM3886 is a high-performance audio power amplifier designed for driving speakers in various applications, such as home audio systems, professional audio equipment, and automotive sound systems. The device operates with a supply voltage range of 10V to 30V and is capable of delivering a significant amount of power while maintaining low distortion levels.

The amplifier features a built-in thermal protection mechanism, which prevents overheating and ensures reliability during operation. Additionally, it has short-circuit protection that safeguards the amplifier and connected components from damage due to excessive current draw. The LM3886 also includes a mute function, allowing for noise-free power-up and power-down transitions, which enhances the overall user experience.

In terms of circuit implementation, the LM3886 can be configured in a variety of ways, including a simple non-inverting amplifier setup or a more complex bridge configuration to achieve higher power output. The device typically requires a few external components, such as resistors and capacitors, to set the gain and stabilize the operation. Proper layout and grounding techniques are essential to minimize noise and ensure optimal performance.

The LM3886's combination of high output power, low distortion, and protective features make it a popular choice for audio amplification applications, providing an excellent balance of performance and reliability.We are using LM3886 which is the revised version of its brother LM3875.Briefly features of LM3886 are; Maximum Output Power: 68W RMS 108W Peak THD: %0.03 at 60W S..
