introduction

This tiny audio amplifier is based on the Texas Instruments TPA2005D1.

Its efficient class-D operation means low heat and long battery life.

It can drive an 8-Ohm speaker at up to 1.4 Watts; it won't shake a stadium,

but it will provide plenty of volume for your audio projects.

Features

• Extremely efficient class-D amplifier
• 1.4W into 8 Ohms
• 2.5V to 5.5V supply
• Fully differential audio inputs, can be ground-referenced as well
• Shutdown input with pullup and LED-follows-shutdown circuitry
• PTH pads provided to change gain resistors if desired (see datasheet for details)
• Solder jumper and header allow addition of a 10k volume control potentiometer (not included)
