3 Description

The LMV55x are high-performance, low-power

operational amplifiers implemented with TI’s

advanced 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 ultra-low power

amplifiers are unity gain stable and provide an

excellent solution for ultra-low power applications

requiring a wide bandwidth.

The LMV55x have a rail-to-rail output stage and an

input common mode range that extends below

ground.

The LMV55x have an operating supply voltage range

from 2.7 V to 5.5 V. 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 and 5-Pin SOT-23

package. The LMV552 is offered in an 8-Pin VSSOP

package. The LMV554 is offered in the 14-Pin

TSSOP.
