LMV393IDR – TEXAS INSTRUMENTS

The Texas Instruments LMV393IDR is a dual comparator integrated circuit housed in a space-saving SOIC-8 package. It operates from a single supply voltage ranging from 1.8V to 5.5V, offering wide flexibility in low-power applications. Each comparator features rail-to-rail input and output stages, enabling full utilization of the supply voltage range and maximizing output swing. The device boasts a typical input offset voltage of only 3mV (max 5mV at 25°C) and a low input bias current of 25nA (max), contributing to high accuracy and reduced power consumption. Propagation delay is typically 15ns, making it suitable for moderately high-speed applications._x000D_

The LMV393IDR’s low supply current (typically 100µA per comparator) makes it ideal for battery-powered systems. Common applications include window comparators, zero-crossing detectors, and simple analog-to-digital converters. Its ability to operate with a low supply voltage and its high input impedance (10¹² Ω) are key advantages when dealing with high-impedance sensors or weak signals. The relatively fast response time, despite low power consumption, makes it a versatile choice for a variety of precision analog signal processing tasks where space and power are critical design constraints. Engineers should consider this part when precise comparison of low-level signals is required within a limited power budget.
