说明

The LMP2014MT is a member of Texas Instruments' new LMPTM precision amplifier family. The LMP2014MT offers unprecedented accuracy and stability 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 LMP2014 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 LMP2014 are rail-to-rail output, a low supply current of 3.7 mA, and wide gain-bandwidth product of 3 MHz. These extremely versatile features found in the LMP2014 provide high performance and ease of use.
