DESCRIPTION

The LMP2012 offers unprecedented accuracy and

stability. 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

LMP2012 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 LMP2012 are rail-rail

output, low supply current of 930 μA, and wide gain•

bandwidth product of 3 MHz. These extremely

versatile features found in the LMP2012 provide high performance and ease of use.

The QMLV version of the LMP2012 has been rated to

tolerate a total dose level of 50krad/(Si) radiation by

test method 1019 of MIL-STD-883.
