{"title":"Pi-DigiAMP+","handle":"pi-digiamp","url":"/products/pi-digiamp","description":"The IQaudIO Pi-DigiAMP+ is a HAT-compliant DAC and amplifier board for the Raspberry Pi, combining a high-quality 24-bit/192 kHz DAC with a 2×20W Class D stereo amplifier on a single board. Based on the Texas Instruments TAS5756m chipset, it delivers full-HD audio quality with no soldering required.\n\nThe board connects directly to the Raspberry Pi's GPIO header using digital I2S audio, reducing CPU load compared to USB audio solutions. When powered externally, the Pi-DigiAMP+ also supplies power to the Raspberry Pi. Driver support is built into Raspbian and compatible with popular audio distributions.\n\nKey Features\n\n\nFull-HD Audio – Up to 24-bit / 192 kHz playback\n\n2×20W Class D Amplifier – Direct speaker output, no external amp needed\n\nTAS5756m DAC – High-quality Texas Instruments chipset\n\nHAT Compliant – EEPROM auto-configuration, standard mounting holes\n\nPowers the Pi – External PSU powers both the amp and the Raspberry Pi\n\nHardware Volume Control – Integrated ALSA volume control\n\nI2S Audio – Digital connection reduces CPU load vs USB audio\n\nGPIO22 Mute Control – Software-controllable amplifier mute\n\nI/O Access – Additional GPIO signals for IR sensors, rotary encoders, I2C devices\n\n\nSpecifications\n\n\nDAC Resolution – Up to 24-bit / 192 kHz\n\nAmplifier – 2×20W Class D stereo\n\nChipset – Texas Instruments TAS5756m\n\nAudio Interface – I2S (via GPIO header)\n\nMute Control – GPIO22 (muted on power-up by default)\n\nPower – External supply required (powers Pi in parallel)\n\nCompatibility – Raspberry Pi 3, 2, A+, B+ (not compatible with original Model A/B)\n\nESD Protection – Advanced on-board protection\n\n\nCompatible Software\n\nRaspbian (built-in driver support)\nRuneAudio, Volumio, Moode, PiCorePlayer, PiMusicBox, OpenELEC\n\n\nIdeal For\n\nStandalone Hi-Fi systems\nRetro radio restorations\nPortable boom boxes and in-car audio\nKiosk and display audio solutions\n\n\nPackage Contents\n\n1× IQaudIO Pi-DigiAMP+\n\n\n\nNote: External power supply, speakers, and Raspberry Pi are sold separately.
