PAM8403 5V Two-channel Stereo Mini Class-D 3W 3W Audio Amplifier

Description The PAM8403 is a 3W 3W, class-D audio amplifier. It offers low THD N, allowing it to achieve high-quality sound reproduction. The new filterless architecture allows the device to drive the speaker directly, requiring no low-pass output filters, thus saving system cost and PCB area. With the same numbers of external components, the efficiency of the PAM8403 is much better than that of Class-AB cousins. It can extend the battery life, which makes it well-suited for portable applications. Features Dual channel stereo, high output power (3 w 3 w power @ 5V and 4 ohms load) Good sound quality Can use computer USB for power supply directly. Double panel wiring solves crosstalk Super mini design allows it to be easily placed in a variety of digital products. 3W Output at 10% THD with a 4ΩLoad and 5V Power Supply Filterless, Low Quiescent Current and Low EMI Low THD N Superior Low Noise Efficiency up to 90% Short Circuit Protection Thermal Shutdown Technical Specifications Model V71 Operating Voltages: 2.5V  to 5.5V Features: Mini amplifier board with compact size, high output power and HD audio.
