Quad comparator for industrial and automotive signal conditioning
The LM2901N/SL65262: It compares two analog voltages per element and pulls the output low when the non-inverting input exceeds the inverting input, making it a workhorse for threshold detection, zero-crossing detectors, and window comparators in industrial control, motor drives, and automotive sensor interfaces.
Wide supply and temperature range fit harsh environments
This comparator operates from a single supply of 2V to 32V or dual supplies of ±1V to ±16V, covering 5V logic, 12V automotive, and 24V industrial rails without a separate regulator. Quiescent current is 2.5mA max across all four comparators, keeping the thermal load low in a tight panel. Input bias current is 0.25µA max at 5V, and input offset voltage is 7mV max at 5V — typical for a general-purpose comparator, adequate for level detection and window comparators where precision below a few millivolts isn't needed.
14-DIP package: rework-friendly, legacy-fit
The 14-pin DIP (0.300" width, 7.62mm pitch) is a through-hole package that hand-solders and reworks easily under a hot-air station or soldering iron — no paste stencil, no reflow profile. The 14-PDIP supplier device package is the same footprint, so any 14-pin DIP comparator can drop in.
