Quad comparator with open-drain outputs — 110 ns propagation delay
The Maxim MAX9095ASD+ is a quad general-purpose comparator in a 14-SOIC package, built around open-drain outputs that let you wire-OR multiple stages or level-shift to a higher-voltage logic rail. The 110 ns maximum propagation delay keeps threshold-detection loops tight for motor-speed sensing, overcurrent trip, and zero-crossing circuits in industrial control.
The 1.8 V minimum supply means it can run from a single lithium cell or a 1.8 V digital core rail, while the 5.5 V ceiling covers standard 5 V logic supplies with margin. Quiescent current maxes at 400 µA across all four channels — a reasonable budget for a multi-channel comparator in a power-constrained design.
Input offset and bias — what the 7 mV and 0.25 µA mean
Maximum input offset voltage is 7 mV at 5 V, and maximum input bias current is 0.25 µA at 5 V. For a general-purpose comparator these numbers are typical of the class — adequate for overvoltage/undervoltage detection, window comparators, and level translators where the threshold is set with a resistor divider. If your application needs sub-millivolt precision (e.g., a current-sense comparator with a 10 mΩ shunt), a precision comparator with lower Vos would be the better fit. The 2 mV typical hysteresis built into the device provides clean switching without external positive feedback, which simplifies the BOM for noisy environments.
The supplier device package is 14-SOIC.
