This week, we worked on getting a bunch of small designs into the pipeline to have a nice crop of new products in a few weeks. Last week, we looked at TDK microphones and were inspired by the T5838 (https://www.digikey.com/short/bzvzbnm9) PDM microphone with configurable low-power wake pin. We also looked at our pile of old 202x protos and re-found the PCM1840 (https://blog.adafruit.com/2021/01/17/leek-pcm1840-quad-input-microphone-i2s-adc-with-hardware-pin-configuration/) so we made a small spin to also create a PCM1820 (https://www.digikey.com/short/5w9v7qtf) a chip with a really funky footprint.

We've also been looking for a replacement for the discontinued UDA1334A (https://www.adafruit.com/product/3678) I2S to line-level output, and it seems like the PCM5102A (https://www.digikey.com/short/n22vn3qn) is a popular option.
