LMP2011 Single/ LMP2012 Dual/ LMP2014 Quad

High Precision, Rail-to-Rail Output Operational Amplifier

General Description

The LMP201X is a new precision amplifier family that offers

unprecedented accuracy and stability at an affordable price

and is offered in miniature packages. 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 tradi-

tional amplifiers. The combination of the LMP201X charac-

teristics 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 pre-

cision and long term stability.

Other useful benefits of the LMP201X are rail-to-rail output,

a low supply current of 930 µA, and wide gain-bandwidth

product of 3 MHz. These extremely versatile features found

in the LMP201X provide high performance and ease of use.
