Design a Custom BoardAbout This Component
Dual low-noise operational amplifier optimized for audio applications with high-speed performance. Features low distortion and noise characteristics suitable for microphone preamplifiers, line drivers, and audio signal conditioning circuits. 8-pin SOIC package for space-constrained audio systems.
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.
