Design a Custom BoardAbout This Component
Dual general-purpose operational amplifier in 8-SOIC package. Features high slew rate and wide bandwidth suitable for audio, instrumentation, and precision signal conditioning applications. Low distortion and noise characteristics make it ideal for audio preamplifiers, summing amplifiers, and active filters.
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.
