LMV7291MG/NOPB TI Comparator | SC-70-5 | 1.8V-5.5V, 1.8µA

Product Overview

The LMV7291MG/NOPB from Texas Instruments is a low-power, single-channel comparator designed for space-constrained and battery-powered applications. Housed in a compact SC-70-5 package, it operates over a wide supply voltage range of 1.8V to 5.5V, making it ideal for portable electronics and industrial sensors. With a typical supply current of only 1.8µA, it extends battery life in always-on systems. The device features push-pull output, eliminating the need for an external pull-up resistor, and offers fast propagation delay of 4µs at 5V.
