Adafruit 987 Stereo 3.7W Class D Audio Amplifier
Product Details
The Adafruit Stereo 3.7W Class D Audio Amplifier features AGC (Automatic Gain Control) and up to 89% efficiency making it ideal for battery powered projects. Optional onboard jumper pins (supplied) let 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. 1.0\u00B5F 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 360kHz 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 1.0\u00B5F capacitors plus 2 x 2-pin screw terminal blocks for the speaker connections and a ;
