LMV321/LMV358/LMV324 Single/Dual/Quad
General Purpose, Low Voltage, Rail-to-Rail Output
Operational Amplifiers
General Description
The LMV358/324 are low voltage (2.7–5.5V) versions of the
dual and quad commodity op amps, LM358/324, which cur-
rently operate at 5–30V. The LMV321 is the single version.
The LMV321/358/324 are the most cost effective solutions
for the applications where low voltage operation, space sav-
ing and low price are needed. They offer specifications that
meet or exceed the familiar LM358/324. The LMV321/358/
324 have rail-to-rail output swing capability and the input
common-mode voltage range includes ground. They all ex-
hibit excellent speed-power ratio, achieving 1MHz of band-
width and 1V/µs of slew rate with low supply current.
The LMV321 is available in space saving SC70-5, which is
approximately half the size of SOT23-5. The small package
saves space on pc 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.
The chips are built with National’s advanced submicron
silicon-gate BiCMOS process. The LMV321/358/324 have
bipolar input and output stages for improved noise perfor-
mance and higher output current drive.
