The wide compliance is the main reason it shows up in motor drives and factory automation panels. The 125°C ceiling covers the hot side of a sealed motor controller or a rooftop telecom power supply. ## Input offset and bias — what trips up a repair bench Maximum input offset voltage is 7 mV at 30 V supply. That is loose enough that a worn-out comparator in a threshold circuit drifts the trip point by several millivolts — the kind of failure that looks like a sensor fault until you scope the reference. Maximum input bias current is 0.25 µA at 5 V, which matters when the source impedance is high, like a thermistor divider. Quiescent current max is 2.5 mA for all four comparators combined — about 0.6 mA per channel. That is low enough to leave headroom on a 24 V loop-powered sensor board without burning the budget.","metaTitle":"LM2901PWRG4 Quad Differential Comparator, -40°C to 125°C","metaDescription":"Texas Instruments LM2901PWRG4 quad differential comparator in TSSOP-14.
