3 Description

The LMV551-Q1 is a high performance, low power

operational amplifier implemented with TI’s advanced

VIP50 process. The LMV551-Q1 features 3 MHz of

bandwidth while consuming only 37 μA of current,

which is an exceptional bandwidth to power ratio in

this op amp class. These amplifiers are unity gain

stable and provide an excellent solution for low power

applications requiring a wide bandwidth.

The LMV551-Q1 has a rail-to-rail output stage and an

input common mode range that extends below

ground.

The LMV551-Q1 has an operating supply voltage

range from 2.7 V to 5.5 V. This amplifier can operate

over a wide temperature range (

−40°C to 125°C)

making it a great choice for automotive applications,

sensor

applications

as

well

as

portable

instrumentation

applications.

The

LMV551-Q1

is

offered in the ultra tiny 5-pin SC70 package.
