Design a Custom BoardAbout This Component
Automotive-qualified dual voltage comparator with wide supply range (2-36V) and low power consumption. Features low input offset voltage (±0.37mV typical), minimal bias current (3.5nA), and TTL/CMOS-compatible open-collector outputs. Suitable for HEV/EV powertrains, body control modules, and industrial sensing applications requiring high reliability across -40°C to +125°C.
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.
