Design a Custom BoardAbout This Component
Single-channel rail-to-rail operational amplifier in SOT-23-5 surface-mount package. Features high-speed performance with typically 200MHz bandwidth and low noise characteristics, suitable for precision signal conditioning, transimpedance amplifiers, and audio applications. Common choice for portable and space-constrained designs.
Package: SOT-23-5 · 5 pins
Why does this need a breakout?
This 0.95 mm pitch SMD package is incompatible with breadboards and difficult to hand-solder. A breakout board brings the five pins to standard 0.1″ spacing, enabling rapid prototyping without reflow equipment. Essential for evaluating precision analog ICs like current-sense amplifiers in development circuits.
