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.

Thermocouple Amplifiers  
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.
