Product description
- Feature This small amplifier is 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 8 speaker at over half a Watt) - making it perfect for portable and battery-powered projects.
- Usage 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.
- Output Power 2.5W at 4 , 10% THD, 1.5W at 8 , 10% THD, with 5.5V Supply.
- Easy to Use 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.
- Specification & Protection & Mode 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 1uA in shutdown mode.
