Adafruit Industries | The Great Search: MCK-less, hardware-configured, stereo line-level output I2S DAC @DigiKey @Adafruit @adafruit | Uploaded September 2024 | Updated October 2024, 3 days ago.
Our UDA1334A (adafruit.com/product/3678) I2S DAC board was discontinued during the part shortage, and we still need to stock a good replacement.

Let's find something that can take its place: we want something low cost - the UDA1334A (digikey.com/short/430z9d79) was under $1 - with a built-in PLL, so no MCK is needed, hardware configuration, so I2C drivers are not needed, and stereo line never output.

We're not expecting to find anything pin-compatible, but we do need to hit all those requirements to make it easy for people to use with microcontrollers / existing digital setups or with SBCs like the Raspberry Pi that don't generate MCK.

It seems like the PCM5102A (digikey.com/short/n22vn3qn) is a popular option.
