6.3mm Stereo Plug (M) – Metal Relief

This incredibly small stereo amplifier is surprisingly powerful – able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10% THD). Inside 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 8ohm 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!

This TDA7297 Audio Amplifier module is just right one for you. This audio amplifier board has no current impact sound when booting, low static noise, and a high quality sound: treble delicate, soft, transparent, no harsh; bass strong, full, strong, and acting freely. The amplifier has been equipped with a heat sink to solve the heat problem, and there is also potentiometer to adjust the loudness, bind to wire the speakers. This module has a max output power up to 15W+15W.

This tiny audio amplifier is based on the Texas Instruments TPA2005D1. Its efficient class-D operation means low heat and long battery life. It can drive an 8-Ohm speaker at up to 1.4 Watts; it won t shake a stadium, but it will provide plenty of volume for your audio projects.
