Overview
The LMV358QDDURG4 is a dual low-voltage operational amplifier produced by Texas Instruments. It is part of the LMV321, LMV358, and LMV324 family, designed for low-voltage operation between 2.7 V and 5.5 V. These amplifiers offer performance specifications that meet or exceed those of the LM358 and LM324 devices, which operate from 5 V to 30 V. The LMV358 is particularly suited for applications requiring low-voltage operation, space savings, and low cost.
