Design a Custom BoardAbout This Component
Monolithic Class AB audio amplifier delivering 3W output into 8Ω loads. Operates from single supply (5V to 15V) with integrated power stage and minimal external components. Commonly used in portable audio equipment, multimedia speakers, and battery-powered applications requiring compact, efficient audio amplification.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
