Innovative LM3886 Board for DIY Audio Projects

This product is well-suited to your exceptional projects. In this section, we cover the special edition board, the expendable type, and 5.1 and/or 7.1 amplifier possibilities.

Let’s talk about the LM3886 Special Edition Amplifier Board

The LM3886 Special Edition Amplifier Board is a high-quality PCB designed for DIY audio enthusiasts who want to build their own high-performance amplifier. This board is compact and includes all the necessary components to get started. This includes the LM3886 amplifier chip, a power supply, and input/output jacks. This unique product has been designed with you, the DIY audiophile, in mind. Its simple set-up makes it a great choice when building your precious amplifier.

The Expendable PCB LM3886

The Expendable PCB LM3886 is a versatile PCB that can be used for many audio amplifier projects. Integrating into a wide range of audio amplifier projects is a breeze. This board has all the necessary components (obviously including the LM3886 amplifier chip). The expandable can be customized to meet your need if you often tinker with audio kits.

5.1 or 7.1 amplifier with LM3886 PCB

Make a 5.1 or 7.1 amplifier with LM3886 PCB

How you can create a 5.1 or 7.1 amplifier with the LM3886 Board

The LM3886 Board can be used to develop both 5.1 and 7.1 amplifiers, but there are differences in how they are built. A 5.1 amplifier has five channels: left, right, center, surround left, and surround right, while a 7.1 amplifier adds two additional channels: surround back left and surround back right.

To create a 5.1 stereo amplifier with the LM3886 Board, the DIY enthusiast must use two LM3886 amplifier chips, one chip for the left channel and another for the right channel. The LM3886 Board can be configured to support multiple input sources, allowing for the connection of various  devices.

For a 5.1 multichannel amplifier, three additional LM3886 amplifier chips are needed: one for the center channel, one for the surround left channel, and one for the surround right channel.

To create a 7.1 stereo amplifier with the LM3886 Board, use two LM3886 amplifier chips for the left and right channels and two additional amplifier chips for the surround left and surround right channels.

For a 7.1 multichannel amplifier, an additional two LM3886 amplifier chips are needed for the surround back left and surround back right channels.

The LM3886 Board can be configured to support up to eight channels, allowing for the creation of a high-performance multichannel audio amplifier. Doing this gives you the much needed options you so crave.

Most Common Applications of LM3886 PCBs

Let’s discuss the most common uses for the LM3886 PCB. Here, we have gathered the most reliable info just for you. Even if you don’t use the board for these purposes, perhaps you’ll get some extra suggestions.

Component and compact stereos: LM3886 PCBs can be used in building components and compact stereos that offer high-quality sound performance. These PCBs can be configured to support a variety of input sources, including RCA jacks, Bluetooth modules, and USB DACs, among others. The stereos these PCBs power are ideal for small rooms and can be easily integrated with existing systems.

LM3886 Performance Aspects

LM3886 Performance Aspects

LM3886 Performance Aspects

The LM3886 is a high-performance integrated circuit that makes exceptional sound performance possible. Here, we will discuss two critical aspects of the chip’s performance: self-peak instantaneous temperature protection circuitry and signal-to-noise ratio, THD+N values, and linearity.

Self-peak instantaneous temperature protection circuitry

The LM3886 features self-peak instantaneous temperature protection circuitry that protects the integrated circuit from thermal overload. This circuitry monitors the temperature of the LM3886 and reduces the output power if the temperature exceeds a predefined threshold. This ensures that the LM3886 operates within safe temperature limits, preventing damage to the integrated circuit and the audio system.

The self-peak instantaneous temperature protection circuitry is particularly useful in high-power audio applications. It’s these instances when the IC can generate significant amounts of heat. With this feature, LM3886 operates safely and reliably, even under high-stress conditions.

Signal-to-noise ratio, THD+N values, and linearity

The LM3886 offers exceptional signal-to-noise ratio, THD+N values, and linearity, which are critical aspects of audio performance.

The signal-to-noise ratio = the ratio of the audio signal to the background noise. The higher the signal-to-noise ratio, the clearer the audio signal. The LM3886 offers a signal-to-noise ratio of 92dB, which is excellent.

THD+N values refer to the total harmonic distortion and noise generated by the integrated circuit. The lower the THD+N values, the cleaner the audio signal. The LM3886 offers THD+N values of 0.03%, which is exceptionally low.

Lastly, linearity refers to the ability of the integrated circuit to reproduce the input signal accurately. The LM3886 offers superb linearity, ensuring the audio signal is reproduced accurately.
