Texas Instruments LMC2001
The LMC2001 is a new precision amplifier that offers unprecedented accuracy and stability at an affordable price and is offered in miniature (SOT23-5) package. 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.FEATURES

DESCRIPTION
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 LMC2001 characteristics makes it a good choice for transducer amplifiers, high gain configurations, ADC buffer amplifiers, DAC I-V conversion, and any other 5V application requiring precision and/or stability. Other useful benefits of the LMC2001 are rail-to-rail output, low supply current of 750µA, and wide gainbandwidth product of 6MHz. The LMC2001 comes in 5 pin SOT23 and 8 pin SOIC.
