Rated for a single supply from 2 V to 30 V, or dual supplies from ±1 V to ±15 V, the LM2901NSR operates on common supply rails.
Maximum input offset voltage is 7 mV at 30 V supply, and maximum input bias current is 0.25 µA at 5 V. The 2.5 mA max quiescent current across all four comparators keeps the power budget lean in always-on sensing blocks.
The base product number is LM2901; variants differ by package and temperature grade. For a pin-compatible alternative within the same family, compare the LM2901DR (SOIC-8, dual) or other LM2901 quad variants in 14-SOIC.
