Design a Custom BoardAbout This Component
Single-channel voltage comparator in SOT-23-5 surface-mount package. Compares two analog input voltages and provides a digital output indicating which input is higher. Suitable for threshold detection, zero-crossing, and window comparator applications in precision measurement and signal conditioning circuits.
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.
