LMV2011
High Precision, Rail-to-Rail Output Operational Amplifier
General Description
The LMV2011 is a new precision amplifier that offers un-
precedented 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 measure
and continually correct the input offset error voltage. The re-
sult is an amplifier which is ultra stable over time and tem-
perature. 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 trans-
ducer amplifiers, high gain configurations, ADC buffer ampli-
fiers, 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 prod-
uct of 3MHz. These extremely versatile features found in the
LMV2011 provide high performance and ease of use.
