描述 The LMP201x series are the first members of TI’s new LMP™ precision amplifier family. The LMP201x series offers unprecedented accuracy and stability in space-saving miniature packaging, offered at an affordable price. This device utilizes patented auto-zero 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 2.7-V to 5-V 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 versatile features found in the LMP201x provide high performance and ease of use.特性 (For VS = 5 V, Typical Unless Otherwise Noted) Low Ensured VOS Over Temperature 60 µV Low Noise with No 1/f 35nV/√Hz High CMRR 130 dB High PSRR 120 dB High AVOL 130 dB Wide Gain-Bandwidth Product 3 MHz High Slew Rate 4 V/µs Low Supply Current 930 µA Rail-to-Rail Output 30 mV No External Capacitors Required
