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.
