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 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test
conditions, see the Electrical Characteristics.
(2) Human Body Model is 1.5 kin series with 100 pF. Machine Model is 0in series with 20 pF.
(3) Shorting output to V+ will adversely affect reliability.
(4) Shorting output to Vwill adversely affect reliability.
(5) The maximum power dissipation is a function of TJ(MAX) , θJA, and TA. The maximum allowable power dissipation at any ambient
temperature is PD = (TJ(MAX)–T A) / θJA. All numbers apply for packages soldered directly into a PC board.
