Single/Dual/Quad, Low Offset, Low Noise, RRO
Operational Amplifiers
General Description
The LMV771/LMV772/LMV772Q/LMV774 are Single, Dual,
and Quad low noise precision operational amplifiers intended
for use in a wide range of applications. Other important char-
acteristics of the family include: an extended operating tem-
perature 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/LMV772Q/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/LMV772Q/LMV774 are guaranteed to operate over
the voltage range of 2.7V to 5.0V and all have rail-to-rail out-
put.
The LMV771/LMV772/LMV772Q/LMV774 family is designed
for precision, 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/
LMV772Q in the space saving MSOP-8 and SOIC-8, and the
LMV774 in TSSOP-14.
