Mini Digital Amplifier Module USB Charger 3W Dual Track with Cable

• Input Voltage: 2.5-5.5 V(USB power supply)
• Output Impedance: 4 ohms
• Efficiency: 90%
• Frequency Response: 150 Hz – 20 kHz
• Input Impedance: 2 Kohm

The Mini Digital Power Amplifiers 3W Dual Track provides Class AB power amplifier performance with Class D amplifier efficiency. The use of low noise, no filter structure can save the traditional D class amplifier output low pass filter. It requires very few external components, thus saving PCB space and system cost, which is ideal for portable applications.

Features:

• A d-type amplifier without a filter, low quiescent current, and low EMI
• When connects with a 4-ohm load and 5V power supply, the output power can be up to 3W
• Low THD, low noise
• Short circuit protection; thermal protection
