DESCRIPTION

The LMP2014MT is a member of Texas Instruments'

new LMPTM precision amplifier family. The

LMP2014MT offers unprecedented 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 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

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 application 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.
