STMicroelectronics LM2901H Quad Voltage Comparator Datasheet
The document describes the LM2901H, a device consisting of four independent precision voltage comparators designed to operate from a single power supply over a wide range of voltages (+2 V to +36 V). A unique characteristic is that the input common-mode voltage range includes ground even when operated from a single positive supply.
The datasheet provides absolute maximum ratings, operating conditions, electrical characteristics including supply current and response time, circuit schematics, package mechanical data for the SO-14 package, and ordering information. It covers both standard and automotive-grade applications.
