TPA6130 is an I2C-controlled Stereo Headphone Amp 🎧🔊📻

While working on our rev B of the DS4420 mono audio amplifier with I2C control, we remembered that we also covered the TPA6130A2 (https://www.digikey.com/en/products/detail/texas-instruments/TPA6130A2RTJR/1531096) on a Great Search video twoish years ago (https://blog.adafruit.com/2022/08/30/the-great-search-stereo-headphone-amplifier-with-i2c-control-thegreatsearch-audio-digikey-digikey-adafruit/) this chip is a headphone amp that can drive 300mW into 16 ohm loads, from differential inputs. The gain can be configured over I2C, mute, and a few other minor configurations. We put a headphone jack on this board to be used instantly for audio projects! Coming soon.

DS4420 I2C audio volume controller, try 2 🎵🔊🔧

We started this breakout for the DS4420 (https://blog.adafruit.com/2021/01/15/ds2240-qt-breakout-routing-timelapse/) I2C-controllable audio volume chip. We got it working but noticed late that it's a 5V-power-only chip and shouldn't be run from 3.3V. Then the parts shortage hit hard, and we couldn't get more samples, so it went on hiatus! But now we're about to get tons of DS4420 chips (https://www.digikey.com/en/products/detail/analog-devices-inc-maxim-integrated/DS4420N/1769257) - so we're respinning it. This time with an AP3602 switched-capacitor booster (https://www.digikey.com/en/products/detail/adafruit-industries-llc/3661/7915572) to give a nice 5V power rail. Coming soon.
