Overview
The LMV358DMR2G is part of the LMV358 series, which includes single, dual, and quad low-voltage operational amplifiers (op-amps) from onsemi. These CMOS op-amps are designed for applications where low power consumption and space-saving packages are critical. They operate from a single-sided power supply ranging from 2.7 V to 5.0 V and feature rail-to-rail output swing, making them ideal for portable, battery-operated equipment. The ultra-low quiescent current and the ability to include ground in the common mode input range enhance their suitability for various applications, including low-side current-shunt measurements.
