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 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. Features Output Power: 2.5W at 4 , 10% THD, 1.5W at 8 , 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 1uA in shutdown mode\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ PAM8302 2.5W This super small mono amplifier is surprisingly powerful.
