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.
