DollaTek Audio Amplifier Board, PAM8406 Digital Power Board 5W+5W Immersion Gold Stereo Amp 2.0 Dual Channel Mini Class D DC5V Amplify DIY Circuit Module

Parameters: audio amplifier board working voltage is DC 5V, output power is 5W (2Ω 5V)/3W (4Ω 5V) / 1.8W (8Ω 5V). Artificial Material: this New-designed 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.
