2) The Pi-DAC+
The Pi-DAC+ is a fully HAT compliant add-on accessory for the Raspberry Pi A+/B+/Pi2/Rpi3.
The Pi-DAC+ takes the digital audio signals (I2S) from the Raspberry Pi and through the onboard
Texas Instruments PCM5122 DAC delivers variable output (hardware volume control) analog audio to
the Pi-DAC+’s Phono connectors. The PI-DAC+ also, via the Texas Instruments TPA6133A
headphone amp, supports the direct use of headphones via the Pi-DAC+’s 3.5mm audio jack.
The Pi-DAC+ can be connected to the Raspberry Pi’s 40way pin header without any additional
soldering.
Component selection and track layout have been in the forefront of our design to ensure noise
immunity and best possible audio playback with the Pi-DAC+.
