Description
For an upgraded version with enhanced performance, please refer to LMV321A, LMV324A, and LMV358A.
The LMV321, LMV358, and LMV324 devices are single, dual, and quad low-voltage (2.7 V to 5.5 V) operational amplifiers with rail-to-rail output swing. These devices are the most cost-effective solutions for applications where low-voltage operation, space saving, and low cost are needed. These amplifiers are designed specifically for low-voltage (2.7 V to 5 V) operation, with performance specifications meeting or exceeding the LM358 and LM324 devices that operate from 5 V to 30 V. With package sizes down to one-half the size of the DBV (SOT-23) package, these devices can be used for a variety of applications.
