Description

This stereo mid-power audio amplifier board is capable of delivering 30W output power per channel into an 8Ohm load based on Class D topology and TI' TPA3118 Amplifier IC, featuring high efficiency up to 92.6% and high sound quality with low distortion and low noise level. Compact size, easy installation and mid power output makes this audio amplifier board suitable for home audio, DIY audio, desktop amplifier, toy audio and demanding industrial applications. A DC10 – 26V power supply is required.

High Quality Audio Performance

By means of dedicated PCB layout design and engineers’ attentive debugging, this mid-power audio amplifier board features such high audio performance that you can get pure enjoy of the music, whose SNR reaches up to 100dB and THD+N performs well as 0.0516% @ 8Ohm, 1W, 1kHz. The output noise level is only 84.8µV.

High Reliability and Long Service Time

The module dissipates only 0.72W with no signal when in ON mode (around 0.07W when in stand-by mode). Excellent heat dissipation eliminates the requirement of an extra heatsink and increases its reliability. Mute and Standby functions are offered with this amplifier module for easy control. Full protection circuit, like over temperature protection, overcurrent protection and reverse polarity protection, is equipped on this board for high reliability and long service time.

Easy for Installation

Four screw holes provided make this amplifier board easy for installation and quick for integration in any cabinet. All the necessary terminals for power supply, audio input and audio output are pre-mounted on the board. Therefore, you only need to plug in the cables and enjoy music without any need of soldering. If you want all the terminals to be mounted for your applications, please contact us. MOQ would be required. Power indicator is provided on board for customers to have an overview of the power condition of the amplifier board.
