The LMV321, LMV358, and LMV324/LMV324S are single, dual, and quad low-voltage (2.7 V to 5.5 V) operational amplifiers with rail-to-rail output swing. The LMV324S is a variation of the standard LMV324 that includes a power-saving shutdown feature that reduces supply current to a maximum of 5 µA per channel when the amplifiers are not needed. The LMV321, LMV358, LMV324, and LMV324S are the most cost-effective solutions for applications where low-voltage operation, space saving, and low price are needed. These amplifiers were designed specifically for low-voltage (2.7 V to 5 V) operation, with performance specifications meeting or exceeding the venerable LM358 and LM324 devices that operate from 5 V to 30 V. Additional features of the LMV3xx devices are a common-mode input voltage range that includes ground, 1-MHz unity-gain bandwidth, and 1-V/µs slew rate.
The document describes the LMV321 (single), LMV358 (dual), LMV324 (quad), and LMV324S (quad with shutdown) operational amplifiers. These devices are designed for low-voltage operation ranging from 2.7 V to 5.5 V and feature rail-to-rail output swing. The LMV324S variant includes a power-saving shutdown mode that reduces supply current to a maximum of 5 µA per channel.
The datasheet provides comprehensive electrical specifications at 2.7 V and 5 V supply voltages, including input offset voltage, bias current, common-mode rejection ratio, and unity-gain bandwidth. It also lists absolute maximum ratings such as supply voltage limits and package thermal impedance for various package types including SC-70 (DCK), SOT-23 (DBV), SOIC, and TSSOP.
