The PmodAMP1 Speaker/Headphone Amplifier (PmodAMP1) amplifies low power audio signals to drive either stereo headphones or a monophonic speaker. The speaker is driven from the left stereo input.

The audio inputs to the module are provided through a Digilent 6-pin Pmod connector. A 1/8-inch stereo audio jack is used for the headphone output and a 1/8-inch mono audio jack is used for the speaker output. An inexpensive speaker and enclosure suitable for use with the PmodAMP1 is available from Digilent.
