Product Information
- It can be powered by computer USB 5V, or phone charger 5V, or lithium battery.
- PAM8403 mini type D digital power amplifier can be easily put in small space of many digital products, high amplification efficiency.
- High efficiency 90%, can provide 3W (left channel)+3W (right channel) when using 4Ω load and 5V power supply.
- Build-in noise reduction circuit, no noise when power on/off, supports short circuit, over current and over temperature protection.
- Type D power amplifier has very high amplification efficiency, sound quality will not be effected by temperature rise, no need of heat sink.
