{"product_id":"adafruit-stereo-2-8w-class-d-audio-amplifier-ts2012","title":"Stereo 2.1W Class D Audio Amplifier - TPA2012","description":"\u003cp\u003eThis incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10% THD).\u003c\/p\u003e\n\u003cp\u003eInside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 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. This board is a welcome upgrade to basic \"LM386\" amps!\u003c\/p\u003e\n\u003cp\u003eThe inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are \"Bridge Tied\" - that means they connect directly to the outputs, no connection to ground. The output is a ~300KHz 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.\u003c\/p\u003e\n\u003cp\u003eComes with a fully assembled and tested breakout board with 1.0uF input capacitors. It also includes a dual mini DIP switch for setting the amplifier gain on the fly, 3.5mm screw-terminal blocks so you can easily attach\/detach your speakers, and some header in case you want to plug it into a breadboard. You will be ready to rock in 15 minutes! \u003cstrong\u003eSpeakers are not included, use any \u003ca href=\"\/en-eu\/products\/mini-speaker-4-3w\" target=\"_blank\"\u003e4 ohm\u003c\/a\u003e or 8 ohm impedance speakers.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOutput Power: 2.1W at 4Ω, 10% THD, 1.4W at 8Ω, 10% THD, with 5V Supply\u003c\/li\u003e\n\u003cli\u003ePSRR: 77 dB typ @ 217 Hz with 6 dB gain\u003c\/li\u003e\n\u003cli\u003eDesigned for use without an output filter, when wires are kept at under 2\"-4\" long\u003c\/li\u003e\n\u003cli\u003eFour pin-selectable gains: 6dB, 12dB, 18dB and 24dB.
