LMP2012QML
Dual High Precision, Rail-to-Rail Output Operational
Amplifier
General Description
Features
The LMP2012 is the first member of National's QML certified
new LMP™ precision amplifier family. 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 configura-
tions, 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.
