Built around the NXP UDA1334A, this versatile DAC supports 3.3V and 5V logic levels and works with MCLK-less interfaces like the Raspberry Pi — a built-in PLL generates the master clock from the bit clock signal automatically.\n\nWith ferrite beads, a low-dropout regulator, and a recommended band-pass filter on board, the output is clean across the full 20 Hz – 20 kHz range with no audible attenuation or distortion. Output is available via a 3.5 mm stereo headphone jack or breadboard-friendly pads.\n\nKey Features\n\n\nNXP UDA1334A Stereo DAC – High-quality I2S to analogue conversion with clean line-level output\n\n3.3V & 5V Logic Compatible – Works with a wide range of microcontrollers and single-board computers\n\nNo MCLK Required – Built-in PLL generates the master clock from the bit clock, ideal for Raspberry Pi\n\nMultiple Data Formats – Supports classic I2S (default), plus 16-bit, 20-bit, and 24-bit left-justified formats\n\n3.5 mm Stereo Jack – Plug in headphones or connect to powered speakers and amplifiers\n\nBreadboard-Friendly Pads – Alternative output for custom wiring and integration\n\nClean Audio Path – Ferrite beads, LDO regulator, and band-pass filter for low-noise output\n\nMute & De-emphasis Pins – Optional hardware mute and de-emphasis filter control\n\n\nIdeal For\n\nRaspberry Pi audio output — works without a master clock\nMicrocontroller projects requiring high-quality stereo DAC output\nHi-fi audio prototypes and media player builds\nAny I2S-capable device needing analogue audio output\n\n\nPackage Contents\n\n1× Adafruit I2S Stereo DAC Breakout (UDA1334A)\n1× Header Strip\n\n\nResources\n\nAdafruit UDA1334A I2S Stereo DAC Guide\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6569,"title":"Default Title","sku":"AF-3678","price":13.53,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
