Introducing the Lonely Binary 2.5W Audio Amplifier - PAM8302: Unleash the Sound Beast!

Prepare to be blown away by the power of Lonely Binary's 2.5W Audio Amplifier - PAM8302. This mighty mini amplifier may be small in size, but it packs a punch, delivering up to 2.5 Watts of pure audio bliss to your 4-8 ohm impedance speakers. Prepare to have your senses rocked like never before!

Inside the heart of this miniature marvel resides a class D controller, capable of running on a voltage range of 2.0V to 5.5VDC. But don't let its size fool you - this amplifier is a powerhouse of efficiency, boasting over 90% efficiency when driving an 8Ω speaker at over half a Watt. It's the perfect match for your portable and battery-powered projects, ensuring your music never misses a beat.

We've got your back when it comes to protection, too. With built-in thermal and over-current safeguards, this amplifier stays cool under pressure. We barely noticed it breaking a sweat! And if that's not enough, we've even included a volume trim pot, allowing you to fine-tune the volume right on the board. It's the epitome of control at your fingertips. Lonely Binary knows how to keep the party going!

The A+ and A- inputs of the amplifier pass through 1.0uF capacitors, providing a fully 'differential' audio experience. Don't have differential outputs? No worries! Simply connect the Audio- pin to ground and let the magic unfold. The output is "Bridge Tied" - meaning the output pins connect directly to the speaker pins without any connection to ground. Get ready for high-frequency 250KHz square wave PWM that gets 'averaged out' by the speaker coil, resulting in incredible sound quality. Be prepared to be transported to audio nirvana.

But that's not all! The Lonely Binary 2.5W Audio Amplifier - PAM8302 comes fully assembled and tested, ready to rock right out of the box. We even include headers for easy breadboard connection and 3.5mm screw-terminal blocks for effortless speaker attachment and detachment. In just 15 minutes, you'll be rocking and rolling with pure audio ecstasy. Please note that the speaker is not included, but fear not - you can use any 4 ohm or greater impedance speaker and let the music take over.

Join the audio revolution with Lonely Binary's 2.5W Audio Amplifier - PAM8302. It's time to unleash the sound beast within. Get yours today and experience audio power like never before. Lonely Binary has your back, delivering pure sonic satisfaction one beat at a time!
