The Great Search: Small 'cap-less' headphone driver
from Adafruit Industries · host Adafruit Industries
For our tiny handheld gamer board, we want to have a headphone driver that does not require a lot of board space. Even if the chip is small, most simple amplifiers require output blocking caps to avoid DC bias on the speakers. But, now-a-days, you can get 'cap-less' drivers that generate a faux-ground. This makes for a very tiny board. Let's find a chip that is small, but not BGA/CSP, that will fit nicely into our design See on Digi-Key at https://www.digikey.com/short/0b3v2192 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/
