Design a Custom BoardAbout This Component
Low-power general-purpose voltage comparator with open-collector output, designed for wide single or dual supply operation (±1.25V to ±18V). Features 150μA supply current, 1nA input bias current, and ±6mV offset voltage. Ideal for line receivers, peak detectors, threshold discrimination, and ground-referenced sensing applications.
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.
