The LMV551/LMV552/LMV554 are high performance, low power operational amplifiers. 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 excellent solution for low power applications requiring a wide bandwidth. 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 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 MSOP package. The LMV554 is offered in the 14-Pin TSSOP.
The LMV551 (along with LMV552 and LMV554) is a high‑performance, low‑power operational amplifier built on National's VIP50 process. It offers a 3 MHz gain‑bandwidth product, rail‑to‑rail output, and a wide supply range of 2.7 V to 5.5 V, making it suitable for automotive, sensor and portable instrumentation applications.
The device is available in ultra‑tiny packages (5‑Pin SC70, 5‑Pin SOT‑23, 8‑Pin MSOP, 14‑Pin TSSOP) and operates over a temperature range of –40 °C to 125 °C. Detailed absolute‑maximum ratings, electrical characteristics, and typical performance graphs are provided for design reference.
