LM393G-S08-R – UTC Dual Differential Comparator IC

Quick Answer The LM393G-S08-R is a dual independent voltage comparator from Unisonic Technologies (UTC). Designed to operate from a single power supply over a wide voltage range (2V to 36V) or dual supplies (±1V to ±18V), it features low supply current, low input bias current, and common-mode input voltage that includes ground. Packaged in SOIC-8, it is ideal for cost-sensitive precision analog comparison applications.
