Design a Custom BoardAbout This Component
General-purpose operational amplifier in compact SOT-23-5 surface-mount package. Single-supply or dual-supply operation with rail-to-rail input and output capabilities. Suitable for audio, instrumentation, and analog signal conditioning applications requiring low noise and moderate gain-bandwidth performance.
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.
