Design a Custom BoardAbout This Component
Dual general-purpose operational amplifier in 8-SOIC surface-mount package. The OPA2277 offers low offset voltage and low noise characteristics suitable for precision signal conditioning, audio circuits, and instrumentation applications. Common configuration for audio preamps, sensor interfaces, and low-noise analog signal processing.
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.
