Overview
The LMV358MM/NOPB from Texas Instruments is a dual low-voltage operational amplifier designed for a wide range of applications requiring low power consumption and high performance. This device is part of the LMV321, LMV358, and LMV324 family, which are low-voltage versions of the traditional LM321, LM358, and LM324 op-amps. The LMV358MM/NOPB operates within a supply voltage range of 2.7 V to 5.5 V, making it suitable for battery-powered systems and other low-voltage applications.
These op-amps are built using Texas Instruments' advanced submicron silicon-gate BiCMOS process, ensuring high speed, low power consumption, and excellent noise performance. They are available in various packages, including the 8-pin VSSOP, which is compact and saves space on printed circuit boards, enabling the design of smaller electronic products.
