Description

PAM8406 5Wx2 Class D Digital Stereo Audio Power Amplifier Module Board with Volume Pots

This miniature PAM8406 module is a 5W class-D stereo audio amplifier. It offers low THD+N and high SNR allowing it to achieve high-quality sound reproduction.

The fully differential output with new filterless architecture (Class-D Mode) allows the device to drive the speakers directly, requiring no low-pass output filters and DC blocking capacitors, saving the system cost and reducing size.

The Pam8406 can operate from a 5V USB power supply or batteries and includes left and right channel volume control potentiometers for ease of use. It is fully protected against faults with short circuit protection and thermal protection.

It can be used in any DIY design requiring a miniature audio amplifier. With efficiency up to 90%, it is well suited to portable and mobile applications operating on battery power.

Features:

Can be powered with a computer USB port, USB power bank or a mobile phone charger to supply the 5V support power
Battery power can also be used
High efficiency: 90%
Provides 5W (left channel) + 5W (right channel) output power at 10% THD+N into a 2Ω speaker load and 5V power supply, 3W into 4Ω and 2W into 8Ω
CMOS class D amplifier design for high efficiency and low cost
Integrated volume controls for left and right channels
Module has short-circuit current and over-temperature protection

Specifications:

Operating voltage: 2.5V-5.5V, recommended 5V
Speaker Load: 2-8 Ohms
