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

Parameters: The operating voltage of the audio amplifier board is 5V DC, the output power is 5W (2Ω 5V) / 3W (4Ω 5V) / 1.8W (8Ω 5V)
Material: This newly designed power amplifier consists of a noble black immersion gold printed circuit board, an imported KEMET speaker capacitor, and a high-capacity filter capacitor for the channels. In addition, we have customized black copper terminal blocks and gold-plated audio input terminal blocks for this new amplifier module.
High Performance: The digital amplifier module has a high efficiency of over 90%, overall harmonic distortion noise is less than 10%, low quiescent current, and noise suppression.
Safe Protection: The Class D two-channel amplifier board is designed with input reverse connection protection, short-circuit protection, and overheat protection; EMI is also allowed to pass through.
Additional Function: It is possible to connect different amplifier types to select different functions (MODE: high power level is type D, low power level is type AB. By default, the power level is high); an external shutdown option is available (SD: the chip will shut down at low power level; the factory default is high).
