Datasheet Amp2

Overview

The HiFiBerry Amp2 is a DAC/amplifier combination for alle Raspberry Pi models featuring a 40-pin GPIO header.

Facts

  • Stereo DAC with sample rates up to 192kHz/24bit
  • Up to 2x30W output power output
  • Uses a single external power supply 12-24V (see below) to power the amplifier and the Raspberry Pi
  • No soldering, comes as a pre-fabricated kit, just plug it onto the Raspberry Pi.
  • Comes with all components required to mount it.

Hardware and speaker connectors

L/R outputs can’t be bridged!

Note that the actual board might look a bit different. Layout and components might change without further notice. We do not guarantee a specific PCB layout or specific components.
