LMV551/LMV552
3 MHz, Micropower RRO Amplifier
General Description
The LMV551/LMV552 are high performance, low power op-
erational amplifiers implemented with National’s advanced
VIP50 process. They feature 3 MHz of bandwidth while con-
suming only 34 μA of current per amplifier, which is an ex-
ceptional bandwidth to power ratio in this op amp class. These
amplifiers are unity gain stable and provide an excellent so-
lution for low power applications requiring a wide bandwidth.
The LMV551/LMV552 have a rail-to-rail output stage and an
input common mode range that extends below ground.
The LMV551/LMV552 have an operating supply voltage
range from 2.7V to 5.5V. These amplifiers can operate over
a wide temperature range (−40°C to +125°C) making them a
great choice for automotive applications, sensor applications
as well as portable instrumentation applications. The LMV551
is offered in the ultra tiny 5-Pin SC70 package. The LMV552
is offered in an 8-Pin MSOP package.
