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 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/LMV772Q/LMV774 to accommodate a broad range of applications.
The LMV771 expands National Semiconductor’s Silicon Dust™ amplifier portfolio offering enhancements 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 output.
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 i...
