Adafruit Stereo 2.8W Class D Audio Amplifier - I2C Control AGC - TPA2016

Key Features: Delivers 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD) Automatic Gain control to keep your audio from clipping or distorting. Class D amp with 89% efficiency when driving an 8ohm speaker at 1.5 Watt Perfect for portable and battery-powered projects Includes 3.5mm screw-terminal blocks so you can easily attach/detach your speakers A mini class D with AGC and I2C control? Yes please! This incredibly small stereo amplifier is surprisingly powerful. It is able to deliver 2 x 2.8W channels into 4 ohm impedance speakers (@ 10% THD) and it has a i2c control interface as well as an AGC (automatic gain control) system to keep your audio from clipping or distorting.If you don't want to use I2C to control it, it does start up on with 6dB gain by default and the AGC set up for most music playing. We do suggest using it with a microcontroller to configure it, however, since its quite powerful. Settings are not stored in the chip, so you'll need to adjust any gain & A
