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.
