Using the digital power amplifier chip TPA3116D2 efficient D class operation
Power amplifier chip has more than 90% power efficiency and low power consumption when standby.
High-level modulation system configuration, highly integrated level reduces the quantity of components.
Self-protection circuit includes over-voltage, under-voltage, overheating, DC detection and short circuit protection, heat-resistant package.
Bluetooth transmission distance is about 10 meters, if used for a speaker, it is best not to use the Bluetooth signal shielding material.
