Giới thiệu [TheVatifly] LM4863 5V Mini Power Amplifier Board 2x3W Dual-Channel HiFi Amp Module HOT tại Lotte Market

Features:
1. It is a dual-sound bridge audio power amplifier chip with stable gain output. When using 5v power supply, it can continuously provide 3W undistorted output power when THD+N is less than 1.0%. In addition, it can drive stereo headphones or can be used as a preamp in single-terminal mode of operation;
2. It is specially designed for high-quality audio systems. It uses surface mount technology to simplify the peripheral circuits of the audio system;
3. It adopts externally controlled low-power shutdown mode, stereo headphone amplifier mode and internal thermal shutdown protection mechanism;
4. Its superior circuit characteristics greatly improve the signal-to-noise ratio and reduce distortion;
5. It has a thermal shutdown protection circuit inside, which can work stably for a long time.
