LPV321 Single/LPV358 Dual/LPV324 Quad

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.
