The Raspberry Pi DigiAMP+ is a high-performance combined DAC and amplifier for your Raspberry Pi (any 40-pin model), offering 24-bit depth and 192kHz (Full HD) audio and the ability to drive 2x 35W speakers - a complete HiFi that’s the size of a deck of cards! Previously known as the IQaudIO DigiAMP+.
The DigiAMP+ uses the Texas Instruments TAS5756M Power DAC to deliver direct connection to passive stereo speakers at up to 2x35W with variable output. It's the ideal board for a Pi-based HiFi project!
DigiAMP+ must be powered from an external 12-24V (DC) power supply to operate, which powers both the HAT and Raspberry Pi (delivers 5.1V at 2.5A). Do not apply power to the Raspberry Pi’s own power input when using DigiAMP+.
The amplifier is by default muted at power-on (mute LED lit). The mute state / LED is under software control (Raspberry Pi GPIO22).
Standard 40-pin header - compatible with any 40-pin Raspberry Pi however please consider the 2.5A max output (may not be ideal for Raspberry Pi 5 depending on otther conencted devices/USB hardware)
