Adafruit 1552 Stereo 2.8W Class D Audio Amplifier (TS2012)

Adafruit Stereo 2.8W Class D Audio Amplifier I2C Control AGC – Adafruit 1552, The Adafruit Stereo 2.8W Class D audio amplifier features AGC (Automatic Gain Control) and up to 89% efficiency making it ideal for battery powered projects. An onboard mini DIP switch lets you control the gain quickly and easily though it can be controlled by signals from off the board. There’s also a shutdown pin for each channel. 1.0µF capacitors on the input channels make them fully differential, the R- and L- pins can be tied to ground if you don’t have differential inputs. The amplifier is intended to drive speakers directly as it outputs 300kHz PWM which the speaker coils average out. That may seem like an odd idea, but the high frequencies cannot be heard. The outputs are Bridge Tied for direct connection to the speakers.Supplied as a fully assembled board, including the 1.0µF capacitors plus 2 x 2-pin screw terminal blocks for the speaker connections and a 1 x 10-pin strip of 0.1in. male header pins for you to solder as needed.
