LM393DR TI Low-Power Dual Comparator | 8-SOIC | 2mV Offset, 0.3μA

Product Overview

The LM393DR from Texas Instruments is a low-power, dual voltage comparator designed for applications requiring low offset voltage and low supply current. It operates from a single power supply over a wide voltage range of 2V to 36V (or ±1V to ±18V for dual supplies). The device features open-collector outputs that can be connected to other open-collector outputs to achieve wired-AND logic. The LM393DR is housed in an 8-pin SOIC package, making it suitable for space-constrained designs.
