Design a Custom BoardAbout This Component
Dual low-noise audio operational amplifier in 8-pin VSSOP package. Features high performance audio specifications with low distortion and noise suitable for preamplifiers, microphone amplifiers, and audio signal conditioning circuits. Designed for professional audio and instrumentation applications requiring precise analog signal processing.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
