PCM5122 is an I2S DAC that does it all 🎶🔧
Having wrapped up our PCM5100 and PCM5102 breakout boards
We stock a lot of chips and development boards that are able to do high quality digital I2S out, which makes for great quality aud
and added them to the Adafruit shop, it's time to explore more DACs we could support. This is the PCM5122

the "big sister" to the PCM5102. Like its sibling, it supports MCLK-less I2S input, making it a great choice for any microcontroller or Raspberry Pi.
It also features a stand-alone "hardware mode," where mute and format can be set via GPIO pins—no I2C configuration required! However, unlike the PCM5102, it also supports I2C/SPI if needed, with built-in filters, numerous configuration flags, and a pin-settable gain option in hardware mode for attenuation.
