This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface. It’s affordable but sounds great! It is compatible with 3.3V – 5V logic levels (a rarity) and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output. It can even handle MCLK-less I2S interfaces such as the Raspberry Pi (which it’s ideal for) – a built in PLL will generate the proper clock from the bitclock signal.
For inputs, you can use classic I2S (the default) or 16-bit, 20-bit or 24-bit left justified data. You can set it up to take an input system/master clock but Adafruit has default-set it to just generate it for you, so you only need to connect Data In, Word Select (Left/Right Clock) and Bit Clock lines. If you want, there’s a mute pin and a de-emphasis filter you can turn on.
Adafruit has used plenty of ferrite beads, a low-dropout regulator, and the recommended band-pass filter so this board produces nice clean output.
Please Note: Minor soldering is required to add the breadboard friendly header
