LMP2012QML
November 30, 2010
Dual High Precision, Rail-to-Rail Output Operational
Amplifier
General Description
The LMP2012 offers unprecedented accuracy and stability.
This device utilizes patented techniques to measure and con-
tinually 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 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 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.
