LM193DT ST Low Power Dual Comparator | 8-SOIC | 2mV Offset, 25nA Bias

Product Overview

The LM193DT from STMicroelectronics is a low-power, dual-channel comparator designed for applications requiring precision voltage comparison with minimal power consumption. Housed in an 8-SOIC package, it operates over a wide supply voltage range from 2V to 36V (single supply) or ±1V to ±18V (dual supply). With a typical offset voltage of 2mV and low input bias current of 25nA, it ensures accurate threshold detection in battery-powered and industrial systems.
