Design a Custom BoardAbout This Component
Quad general-purpose operational amplifier in 14-pin SOIC surface-mount package. The OPA4277 integrates four independent op-amp circuits optimized for precision analog signal conditioning, summing, differentiation, and buffering applications. Suitable for instrumentation, audio, and mixed-signal designs requiring multiple amplifier channels in compact form factor.
Package: SOIC-14 (3.9×8.7mm) · 14 pins
Why does this need a breakout?
Manual soldering of 1.27mm pitch SOIC-14 leads is tedious and error-prone; a breakout board eliminates this with pre-soldered pads and convenient 0.1-inch headers for breadboard prototyping. Ideal for developing capacitive touch sensor applications or other logic circuits without the fine-pitch assembly hassle.
