Design a Custom BoardAbout This Component
Single-channel general-purpose operational amplifier with 3V to 36V supply range and rail-to-rail output. Features low offset voltage (±3mV), low quiescent current (100μA), and 0.9MHz bandwidth suitable for sensor interfaces, motor control, and audio applications. Includes input common-mode range extending to negative rail and can function as a comparator.
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.
