Product details

Pump up the volume with this 20 W stereo amplifier! This slim little card has a class D amplifier on board, which provides 2 channels of 4-8 ohm impedance speakers with 20W each. Supply it with 5-12VDC using the integrated DC jack and stereo line level into the 3.5mm stereo system, plug in the headphone jack and easily disturb. Because it's Class D, its completely cool running, no heat sinks are required and it's extremely efficient - up to 93% efficiency makes it great for portable or battery powered rigs. We like the MAX9744 amplifier at the heart of this card because it is very easy to use, but it also has both analog and digital volume control capabilities. Use a single 1K pot (we included one) to set the following volume analog type. Or connect it to your favorite microcontroller and send I2C commands to set 64 levels of volume gain. We took this nice chip and packed it for you in a breakout, with reverse polarity protection, jacks and terminal blocks, i2c-level shift and a point for soldering into a volume pot. Each order comes with a MAX9744 breakout board with all surface mounted parts fully assembled and tested. We also include 3 x 2-pin and 1 x 3-pin terminals, a 470uF power filter capacitor and 1K trim pot. To use this board, a little soldering is required to attach the terminals and other components, but it is fairly simple and should take less than 15 minutes. See our detailed tutorial for assembly instructions and general use.
