Maximum input offset voltage is 7mV at 30V supply — tight enough for window comparators and zero-crossing detectors in motor-drive current sensing, where a few millivolts of error shifts the trip point by a fraction of the sense-resistor drop. Maximum input bias current is 0.25µA at 5V, so high-impedance sources like thermistors or photodiodes see negligible loading — the bias current won't pull the threshold off by more than a few millivolts even with 10kΩ source resistance. ## Open-collector output and quiescent current Total quiescent current for all four comparators is 2.5mA max — low enough that the part adds negligible drain in battery-backed or always-on monitoring circuits.","metaTitle":"LM2901NG4 Quad Comparator, Open-Collector, -40°C to 125°C","metaDescription":"Texas Instruments LM2901NG4 quad general-purpose comparator with open-collector outputs. 2V to 30V supply, -40°C to 125°C range.
