LMP2011

LMP2011 Single/ LMP2012 Dual/ LMP2014 Quad High Precision, Rail-to-Rail Output Operational Amplifier PRELIMINARY October 2004 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 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.
