IQaudio DAC is an audio output HAT for all generations of Raspberry Pi from Raspberry Pi 1 Model B onwards, and supports 24‑bit 192kHz high-resolution digital audio. It uses the Texas Instruments PCM5122 DAC to deliver stereo analogue audio to a pair of phono connectors, and also supports a dedicated headphone amplifier.
