LMV551/LMV552/LMV554
3 MHz, Micropower RRO Amplifiers
General Description
The LMV551/LMV552/LMV554 are high performance, low
power operational amplifiers implemented with National’s ad-
vanced VIP50 process. They feature 3 MHz of bandwidth
while consuming only 37 μA of current per amplifier, which is
an exceptional bandwidth to power ratio in this op amp class.
These amplifiers are unity gain stable and provide an excel-
lent solution for low power applications requiring a wide band-
width.
The LMV551/LMV552/LMV554 have a rail-to-rail output stage
and an input common mode range that extends below ground.
The LMV551/LMV552/LMV554 have an operating supply
voltage range from 2.7V to 5.5V. These amplifiers can oper-
ate over a wide temperature range (−40°C to 125°C) making
them a great choice for automotive applications, sensor ap-
plications as well as portable instrumentation applications.
The LMV551 is offered in the ultra tiny 5-Pin SC70 and 5-Pin
SOT-23 package. The LMV552 is offered in an 8-Pin MSOP
package. The LMV554 is offered in the 14-Pin TSSOP.
