Design a Custom BoardAbout This Component
Low-power dual voltage comparator operating from single or split supplies (±2V to ±36V). Features 0.4 mA supply current, 25 nA input bias current, and rail-to-rail input common-mode range. TTL/CMOS compatible outputs with 250 mV saturation voltage. Ideal for battery-powered applications, signal conditioning, and window comparators.
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.
