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: an extended operating temperature
range of −40°C to 125°C, the tiny SC70-5 package for the
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. The LMV771 expands National
Semiconductor's Silicon Dust ™ amplifier portfolio offering en-
hancements 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 the 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 the space saving MSOP-8 and SOIC-8, and the LMV774
in TSSOP-14.
