introduction

TPA2005D1.jpg

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)
