-Descripcion Original:

Adafruit Part Number: 2130 // Stock Type: Breakout Boards >> Amplifiers/Sound // In Stock & Ready to Ship // This super small mono amplifier is surprisingly powerful - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers. Inside the miniature chip is a class D controller, able to run from 2.0V-5.5VDC. Since the amp is a class D, its very efficient (over 90% efficient when driving an 8Î speaker at over half a Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. There's even a volume trim pot so you can adjust the volume on the board down from the default 24dB gain. This board is a welcome upgrade to basic LM386 amps! The A+ and A- inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the Audio- pin  to ground. The output is Bridge Tied - that means the output pins connect directly to the speaker pins, no connection to ground. The output is a high frequency 250KHz 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. We also include header to plug it into a breadboard and a 3.5mm screw-terminal blocks so you can easily attach/detach your speaker. You will be ready to rock in 15 minutes! Output Power: 2.5W at 4Î, 10% THD, 1.5W at 8Î, 10% THD, with 5.5V Supply50dB PSRR at 1KHzFilterless design, with ferrite bead + capacitors on output.Fixed 24dB gain, onboard trim potentiometer for adjusting input volume.Thermal and short-circuit/over-current protectionLow current draw: 4mA quiescent and 1uA in shutdown mode
