LMV771/LMV772/LMV774

Single/Dual/Quad, Low Offset, Low Noise, RRO

Operational Amplifiers

General Description

The LMV771/LMV772/LMV774 are Single, Dual, and Quad

low noise precision operational amplifiers intended for use in

a wide range of applications. Other important characteristics

of the family include extended operating temperature range,

−40˚C to 125˚C, tiny SC70-5 package for LMV771, and low

input bias current.

The extended temperature range of −40˚C to 125˚C allows

the LMV771/LMV772/LMV774 to accommodate a broad

range of applications. LMV771 expands National Semicon-

ductor’s Silicon Dust™ amplifier portfolio offering enhance-

ments in size, speed, and power savings. The LMV771/

LMV772/LMV774 are guaranteed to operate over the

voltage range of 2.7V to 5.0V and all have rail-to-rail output.

The LMV771/LMV772/LMV774 family is designed for preci-

sion, low noise, low voltage, and miniature systems. These

amplifiers provide rail-to-rail output swing into heavy loads.

The maximum input offset voltage for LMV771 is 850 µV at

room temperature and the input common mode voltage

range includes ground.

The LMV771 is offered in the tiny SC70-5 package, LMV772

in space saving MSOP-8 and SOIC-8, and the LMV774 in

TSSOP-14.
