LM393DGKR

LM393DGKR Description

The LM393DGKR from Texas Instruments is a dual differential comparator designed for general-purpose applications. Packaged in an 8-VSSOP and available in Tape & Reel (TR), this surface-mount IC operates over a wide supply voltage range (2V–36V single supply, ±1V–18V dual supply), making it highly versatile. With a quiescent current as low as 2.5mA (max) and input bias current of 0.25µA (max), it ensures efficient power consumption. The device features low input offset voltage (5mV max @ 30V) and a 20mA output current capability, enabling precise and reliable signal comparison. Its RoHS3 compliance and REACH-unaffected status ensure environmental and regulatory adherence.

LM393DGKR Features

• Dual Comparator Design: Two independent comparators in a single package, reducing board space and cost.
