This document is a datasheet for the TS391, a low-power single voltage comparator designed to operate from a wide single supply voltage range (+2 V to +36 V) or dual supplies. Key features include very low supply current (0.2 mA), low input bias current (25 nA typ.), and an input common-mode voltage range that includes ground.
The datasheet provides comprehensive technical data including absolute maximum ratings, electrical characteristics such as input offset voltage and response time, and detailed mechanical drawings for the SOT23-5L and DFN8 2x2 mm packages. It also lists ordering information for various temperature ranges and package types.
