DROK Audio Amplifier Board, 5W+5W Mini Amplifier Board PAM8406 DC 5V Digital Stereo Power Amp 2.0 Dual Channel Class D Amplify Module for Speaker Sound System DIY

Parameters: DROK audio amplifier board working voltage is DC 5V, output power is 5W (2Ω 5V)/3W (4Ω 5V) / 1.8W (8Ω 5V). Input method is monaural input.
Artificial Material: this New-designed mini power amplifier is made of noble black immersion gold circuit board, imported KEMET speaker capacitor, large-capacity filter capacitor for channels. Besides, we customized black copper terminal blocks and gold-plated audio input terminal blocks for this new amplifier module.
High Performance: the digital amplifier module is with high efficiency of over 90%, general harmonic distortion noise is less than 10%, low quiescent current and noise suppression.
Safe Protection: the class D dual-channel amp board is designed with input reverse connection protection, short circuit protection, over heat protection; what's more, EMI is allowed to pass.
Additional Function: it is available to connect amplifier type to choose different function (MODE: high electricity level is Type D, low electricity level is Type AB. Factory defaults high electricity level); available to add an external Shutdown (SD: the chip will be Shutdown at low electricity level, factory default high electricity level.
