DESCRIPTION

The LMV2011 is a new precision amplifier that offers

unprecedented accuracy and stability at an affordable

price and is offered in a miniature (5-pin SOT-23)

package and in an 8-lead SOIC package. This device

utilizes patented techniques to measure and

continually correct the input offset error voltage. The result is an amplifier which is ultra stable over time

and temperature. It has excellent CMRR and PSRR

ratings, and does not exhibit the familiar 1/f voltage

and current noise increase that plagues traditional

amplifiers. The combination of the LMV2011

characteristics makes it a good choice for transducer

amplifiers, high gain configurations, ADC buffer

amplifiers, DAC I-V conversion, and any other 2.7V-

5V application requiring precision and long term

stability.

Other useful benefits of the LMV2011 are rail-to-rail

output, a low supply current of 930μA, and wide gain-

bandwidth product of 3MHz. These extremely

versatile features found in the LMV2011 provide high

performance and ease of use.
