General Purpose, Low Voltage, Low Power, Rail-to-Rail
Output Operational Amplifiers
General Description
The LPV321/358/324 are low power (9 µA per channel at
5.0V) versions of the LMV321/358/324 op amps. This is
another addition to the LMV321/358/324 family of commod-
ity op amps.
The LPV321/358/324 are the most cost effective solutions
for the applications where low voltage, low power operation,
space saving and low price are needed. The LPV321/358/
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 5 kHz of band-
width with a supply current of only 9 µA.
The LPV321 is available in space saving 5-Pin SC70, which
is approximately half the size of 5-Pin SOT23. The small
package saves space on PC boards, and enables the design
of small portable electronic devices. It also allows the de-
signer 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 LPV321/358/324 have
bipolar input and output stages for improved noise perfor-
mance and higher output current drive.
