LMP2015/LMP2016 are the first members of National's new LMPTM precision amplifier family. They offer unprecedented accuracy and stability in space-saving miniature packaging at an affordable price. These devices utilize patented techniques to measure and continually correct the input offset error voltage. The result is a series of amplifiers that are ultra stable over time and temperature. They have excellent CMRR and PSRR ratings and do not exhibit the familiar 1/f voltage and current noise increase that plagues traditional amplifiers. The combination of characteristics makes the LMP2015/LMP2016 good choices for transducer amplifiers, high gain configurations, ADC buffer amplifiers, DAC I-V conversion, or any other 2.7V-5V application requiring precision and long-term stability. Other useful benefits of the LMP2015/LMP2016 are rail-to-rail output, a low supply current of 930 µA, and a wide gain bandwidth product of 3 MHz. These extremely versatile features provide high performance and ease of use.
The LMP2015 (single) and LMP2016 (dual) are high‑precision, rail‑to‑rail output operational amplifiers designed for transducer, ADC, DAC, and instrumentation applications. They feature low supply current, wide gain‑bandwidth product, and excellent CMRR and PSRR performance.
