LMP2014MT

Quad High Precision, Rail-to-Rail Output Operational

Amplifier

General Description

The LMP2014MT is a member of National’s new LMP

TM

precision amplifier family. The LMP2014MT offers unprec-

edented accuracy and stability while also being offered at an

affordable price. This device utilizes patented techniques to

measure and continually correct the input offset error volt-

age. 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 LMP2014 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 ap-

plication requiring precision and long term stability.

Other useful benefits of the LMP2014 are rail-to-rail output, a

low supply current of 3.7 mA, and wide gain-bandwidth

product of 3 MHz. These extremely versatile features found

in the LMP2014 provide high performance and ease of use.
