Datasheet Amp100

Overview

The HiFiBerry Amp100 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, based on the HiFiBerry DAC2 Pro design
Up to 2x100W output power output
Can be extended with the HiFiBerry DSP add-on board
Onboard TOSLink input/output (requires DSP add-on board)
Uses a single external power supply 12-30V 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

1	Power input, barell jack
2	TOSLink input connector (requires DSP add-on)
3	Toslink output connector (requires DSP add-on)
4	Power connector, screw terminal
5	DSP I2S output connector
6	DSP I2S output connector
7	Right speaker output
8	Left speaker output
9	DSP add-on 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.

The Amp2 will power the Raspberry Pi. It is powerful enough for any Pi up to the Pi4B. Note that additional hardware drawing lots of power (e.g. hard disks, displays) might require an external power supply.
