LM393DT ST Low-Power Dual Comparator | 8-SOIC | 2mV Offset, 1.3μA

Product Overview

The LM393DT from STMicroelectronics is a low-power, low-offset voltage dual comparator designed for applications requiring high precision and minimal power consumption. Housed in an 8-SOIC package, this device operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies). It features an open-collector output that allows wired-AND connections, making it versatile for various logic and control systems. The LM393DT is characterized by its low supply current (0.4mA typical) and fast response time (1.3μs), making it suitable for battery-powered and portable equipment.
