DIY AC And DC 5V CM2038 USB Mini Amplifier Module With 5W Dual Channel High-fidelity Finished Board And Shell

Overview: The CM2038 is a dual BTL audio power amplifier.When the power supply voltage is 6V, 3.5W output power (peak 5W) can be supplied to the 4 load while ensuring THD is less than 10% and 2.2W output power can also be supplied to the 8 load. The audio power amplifier has few external components and sound quality. The PM2038 circuit features external control, low-power shutdown mode and internal over-temperature protection, and reduces "start-up surge pulses" in the circuit. Parameter: Load: 4 Power: typical 3.5W, peak 5W Voltage: DC AC 6V Shutdown current typical: 0.7A Operating voltage range: DC AC 2V-6V Built-in startup surge suppression circuit Built-in overheat protection circuit Specification: Circuit board: 50*45*25mm (length*width is PCB specification, height includes components) Shell: 65*60*45mm (length*width*hight) Note: With a film on the shell surface, tear it off. Package included: 1 X USB mini amplifier module with shell 1 X USB power cable 1 X AUX audio cable
