MAX9768BETG+T

The MAX9768BETG+T is a mono Class-D audio power amplifier with integrated volume control, manufactured by Analog Devices and supplied in a compact 24‑lead TQFN package. Its high‑efficiency Class‑D topology, combined with spread‑spectrum modulation, minimizes electromagnetic interference while delivering robust output into low‑impedance speaker loads. A fully differential input stage provides strong rejection of common‑mode noise, and an I²C‑compatible serial interface enables precise digital volume adjustment, eliminating the need for external analog control components. Built‑in protection features guard against output short‑circuits, thermal overload, and pop‑and‑click transients during power cycling.

Typical deployments span portable wireless speakers, industrial intercom and paging panels, medical‑alarm sounders, and cabin audio modules in aerospace and defense platforms where compact footprint, high electrical efficiency, and predictable thermal behavior are essential. The device is well‑suited for embedded systems requiring a reliable, low‑complexity audio output stage. As an active production part, the MAX9768BETG+T carries no immediate end‑of‑life risk; the “+T” suffix designates tape‑and‑reel packaging for automated assembly. It is rated for the industrial temperature range of -40 °C to +85 °C, making it appropriate for commercial, industrial, and certain high‑reliability applications where additional derating or qualification screening may be applied.
