Design a Custom BoardAbout This Component
Dual-channel zero-drift operational amplifier in 8-pin VSSOP package. Features precision amplification with extremely low offset voltage drift and low noise, making it ideal for instrumentation, sensor signal conditioning, and precision analog circuits. Suitable for battery-powered and portable applications requiring minimal power consumption.
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.
