Audio Amplifier Stereo 3W+3W PAM8403 with Volume Control
PRODUCT ID: MOD-BUZ-003
This PAM8403 module is a 3W, Class-D stereo audio amplifier. It offers low THD+N, allowing it to achieve high-quality sound reproduction, and all these packed in a form factor about the size of a postage stamp.
It can operate from a 5V USB power supply or batteries, but make sure voltage is not more than 6V! Noise canceling circuit is built into the amplifier board and what's good about this module is that you can power on / off without popping noise! Integrated in the volume control potentiometer is a power switch for ease of use. Just hook up the power and in / out lines and you're good to go!
This module has short-circuit current protection, under-voltage lockout and over-temperature protection (shuts down at an internal temperature of 140°C ±15°C).
Output is CMOS BTL drive mode, and the 4 wires are completely independent, do not connect it together.
- Input Voltage: 2.5 - 5.5V
- Output Power: 3W + 3W (4Ω)
- SNR: 90dB
- Efficiency: > 90%
