8 Detailed Description
8.1 Overview
The LMV321, LMV358, LMV324, and LMV324S devices are single, dual, and quad low-voltage (2.7 V to 5.5 V)
operational amplifiers with rail-to-rail output swing. The LMV324S device, which is a variation of the standard
LMV324 device, includes a power-saving shutdown feature that reduces supply current when the amplifiers are
not needed. Channels 1 and 2 together are put in shutdown, as are channels 3 and 4. While in shutdown, the
outputs actively are pulled low.
The LMV321, LMV358, LMV324, and LMV324S 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. 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 LMV321 device is available in the ultra-small package, which is approximately one-half the size of the DBV
(SOT-23) package. This package saves space on printed circuit boards and enables the design of small portable
electronic devices. It also allows the designer to place the device closer to the signal source to reduce noise
pickup and increase signal integrity.
