General Purpose, Low Voltage, Rail-to-Rail Output
Operational Amplifiers
General Description
The LMV358/LMV324 are low voltage (2.7–5.5V) versions of
the dual and quad commodity op amps, LM358/LMV324,
which currently operate at 5–30V. The LMV321 is the single
version.
The LMV321/LMV358/LMV324 are the most cost effective
solutions for the applications where low voltage operation,
space saving and low price are needed. They offer specifica-
tions that meet or exceed the familiar LM358/LMV324. The
LMV321/LMV358/LMV324 have rail-to-rail output swing ca-
pability and the input common-mode voltage range includes
ground. They all exhibit excellent speed to power ratio,
achieving 1 MHz of bandwidth and 1 V/µs of slew rate with
low supply current.
The LMV321 is available in the space saving 5-Pin SC70,
which is approximately half the size of the 5-Pin SOT23. 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 sili-
con-gate BiCMOS process. The LMV321/LMV358/LMV324
have bipolar input and output stages for improved noise per-
formance and higher output current drive.
