      Sure Electronics AA-AB32178 2x50W 4 Ohm Class D Audio Amplifier Board - TPA3116


      Don't let the size fool you, the TPA3116 amp board delivers 2 x 50W into 4Ω loads. This device operates from 8V to 26V and provides a high PSRR, eliminating the need for a regulated power supply. The TPA3116 has the ability to be used as a small car amplifier, because it offers up to 90% efficiency at 12 VDC.


      Comprehensive click-and-pop reduction circuitry minimizes noise coming into and out of shutdown or mute. Work this amp board into your next small portable speaker project and enjoy the sound without the annoying pop sound when you turn it off.

      Geplaatst in een boombox buiten onder de veranda met Volumio icm touchscreen. Goede vervanging voor de 2 x 15 W Sure Electronics versterker die ik eeder had ingebouwd, maar op feestjes net wat te weinig vermogen bood.

      Klingt sehr gut - leider keine schutzschaltung an bord = es plöppt beim Ausschalten Am externen Netzteil Passte der Stecker nicht (war zu groß) Wird überraschend auch bei leisen Dauerbetrieb am Kühlkörper sehr warm!
