Output Operational Amplifiers
General Description
The LPV321/358/324 are low power (9µA per channel at
5.0V) versions of the LMV321/358/324 op amps. This is an-
other addition to the LMV321/358/324 family of commodity
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 exhibit excellent speed-power ratio, achieving
152 KHz of bandwidth with a supply current of only 9µA.
The LPV321 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 LPV321/358/324 have bi-
polar input and output stages for improved noise perfor-
mance and higher output current drive.
