Overview
The LMV358IDGKR is a dual low-voltage operational amplifier designed by Texas Instruments. It is part of the LMV321, LMV358, and LMV324 family, which are known for their cost-effective, space-saving, and low-power operation. These amplifiers are optimized for low-voltage applications, operating within a range of 2.7 V to 5.5 V, and offer performance specifications that meet or exceed those of the traditional LM358 and LM324 devices. The LMV358IDGKR is particularly useful in applications where low power consumption, small package size, and rail-to-rail output swing are critical.
