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

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 4Ω load while ensuring THD is less than 10%, and 2.2W output power can also be supplied to the 8Ω 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.
