Stock Details
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 & AGC amplification settings every time the amp is powered up. Inside the miniature chip is a class D controller able to run from 2.7V5.5VDC. Since the amp is a class D it's incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 Watt) making it perfect for portable and batterypowered projects. It has built in thermal and overcurrent protection but we could barely tell if it got hot. This board is a welcome upgrade to basic LM386 amps! The inputs of the amplifier go through 1.0uF capacitors so they are fully 'differential' if you don't have differential outputs simply tie the R and L to ground. The outputs are Bridge Tied that means they connect directly to the outputs no connection to ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil the high frequencies are not heard. All the above means that you can't connect the output into another amplifier it should drive the speakers directly.
Comes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include 3.5mm screwterminal blocks so you can easily attach/detach your speakers and some header in case you want to plug it into a breadboard. Speakers are not included use any 4 ohm or 8 ohm impedance speakers.
