LMV2011
High Precision, Rail-to-Rail Output Operational Amplifier
LMV2011 High Precision, Rail-to-Rail Output Operational Amplifier
April 2004
General Description
The LMV2011 is a new precision amplifier that offers unprecedented 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 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.
