Reference Design of Digilent Pmod AMP3

This is a reference design of Digilent Pmod AMP3 – RS Part Number (134-6461). The Digilent Pmod AMP3 was converted into DesignSpark PCB format. Download link of the project files and the datasheet of Digilent Pmod AMP3 can be found in this article.

The Digilent Pmod AMP3 is a Pmod 2W Class-D amplifier module. It uses I²C standard to transmit audio. The digital volume and dynamic range can be change via I²C interface. It also provides a standalone mode that does not require I²C interface.

• 2W Class-D amplifier
• 2x 3.5mm audio jack with left and right channel separation
• Volume and dynamic control for each channel
• Stand-alone mode
