Design a Custom BoardAbout This Component
Dual independent low-power voltage comparator operating from single supply 2V to 36V or dual supplies ±1V to ±18V. Features 0.4mA supply current, 25nA input bias current, and TTL/CMOS compatible outputs with 250mV saturation voltage. Ideal for threshold detection, window comparators, and analog signal conditioning in 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.
