FEATURES
DESCRIPTION
The LMP201X series are the first members of TI's
new LMPTM precision amplifier family. The LMP201X
series offers unprecedented accuracy and stability in
space-saving miniature packaging 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 LMP201X
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 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.

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.
