LMV3xx Low-Voltage Operational Amplifiers Texas Instruments LMV3xx Low-Voltage Operational Amplifiers are single, dual, and quad low-voltage (2.7V to 5.5V) operational amplifiers with rail-to-rail output swings. These devices are the most cost-effective solutions for applications where low-voltage operation, space-saving, and low cost are needed. The Texas Instruments LMV3xx amplifiers are designed specifically for low-voltage (2.7V to 5V) operation with performance specifications meeting or exceeding the LM358 and LM324 devices that operate from 5V to 30V. With package sizes down to one-half the size of the DBV (SOT-23) package, these devices can be used for various applications.
