LM2901PWR

LM2901PWR Description

The LM2901PWR from Texas Instruments is a quad differential comparator designed for general-purpose applications. Packaged in a 14-pin TSSOP and available in Tape & Reel (TR), this surface-mount IC operates over a wide supply voltage range (2V–30V single or ±1V–15V dual), making it versatile for various circuit designs. It features low input bias current (0.25µA @ 5V) and minimal quiescent current (2.5mA max), ensuring efficient power consumption. With a maximum input offset voltage of 7mV @ 30V, it delivers high precision in comparison tasks. The device is RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited), ensuring reliability in manufacturing and environmental compliance.
