LMV2011

High Precision, Rail-to-Rail Output Operational Amplifier

General Description

The LMV2011 is a new precision amplifier that offers unprec-

edented accuracy and stability at an affordable price and is

offered in miniature (SOT23-5) package and in 8 lead SOIC

package. This device utilizes patented techniques to mea-

sure 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 ap-

plication 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 prod-

uct of 3MHz. These extremely versatile features found in the

LMV2011 provide high performance and ease of use.
