Design a Custom BoardAbout This Component
Dual independent precision voltage comparator with low input offset voltage (5 mV max) and low input bias current (25 nA). Operates on single supplies 2.0-36 VDC or split supplies ±1.0-±18 VDC with minimal current drain (0.4 mA). Ideal for sensor signal conditioning, window comparators, and threshold detection in consumer, automotive, and industrial applications.
Package: SOIC-8 (3.9×4.9mm) · 8 pins
Why does this need a breakout?
An 8-pin SOIC with 1.27mm pitch is too fine for breadboards and hand-soldering without a microscope. A breakout board routes these pins to standard 0.1" headers, enabling rapid prototyping and reliable connections for op-amps, transceivers, and small power MOSFETs without requiring reflow equipment.
