Design a Custom BoardAbout This Component
Dual independent voltage comparator operating from 2-36V supply with low offset voltage (±4mV max), low input bias current (3.5nA typ), and 1µsec response time. Features open-collector outputs compatible with TTL/CMOS logic and wide common-mode input range including ground. Ideal for motor control, power supplies, and industrial automation applications.
Package: MSOP-8 · 8 pins
Why does this need a breakout?
The 0.65mm pitch and tiny 3×3mm form factor make hand soldering challenging and impractical for breadboard prototyping. A breakout board converts this compact SMD package into a standard header layout, enabling reliable connections and rapid iteration without specialized soldering equipment or rework risk.
