Product Details
  • Delivers up to 2.5 Watts into 4-8 ohm impedance speakers
  • Very efficient Class-D controller amp
  • Built in thermal and over-current protection
  • Fixed 24dB gain, onboard trim potentiometer for adjusting input volume.
  • Output is "Bridge Tied" meaning the output pins connect directly to the speaker pins, no connection to ground

  • Manufacturer: Adafruit
  • Model Number: 2130
  • Package Quantity: 1
  • Part Number: 2130

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 8Ω 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! Speaker is not included, use any 4 ohm or greater impedance speaker. Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Supply 50dB PSRR at 1KHz Filterless design, with ferrite bead + capacitors on output. Fixed 24dB gain, onboard trim potentiometer for adjusting input volume. Thermal and short-circuit/over-current protection Low current draw: 4mA quiescent and 0.5mA in shutdown (due to pullup resistor on SD pin) Note: The terminal block included with your product may be blue or black.
