Overview
The LMV358IDR2G is a dual low-voltage operational amplifier produced by onsemi. It is part of the LMV321, LMV358, and LMV324 family, which are designed as cost-effective solutions for applications requiring low power consumption and space-saving packages. These amplifiers operate from a single-sided power supply of 2.7 V to 5.5 V and feature rail-to-rail output swing, making them ideal for applications where optimal signal-to-noise performance is crucial. The ultra-low quiescent current and small package options make them suitable for portable, battery-operated equipment and other applications where power efficiency is key.
