LINEAR TECHNOLOGY  LT1991AIMS#PBF  差分放大器, 可选增益, 1 放大器, 50 µV, 560 kHz, -40 °C, 85 °C

The is a precision Operational Amplifier with eight precision resistors to form one-chip solution for accurately amplifying voltages. Gains from -13 to 14 with a gain accuracy of 0.04% can be achieved using no external components. The device is particularly well suited for use as a difference amplifier, where the excellent resistor matching results in a common mode rejection ratio of greater than 75dB. The amplifier features a 50µV maximum input offset voltage and a gain bandwidth product of 560kHz. The device operates from any supply voltage from 2.7 to 36V and draws only 100µA supply current on a 5V supply. The output swings to within 40mV of either supply rail. The resistors have excellent matching, 0.04% over temperature for the 450k resistors. The matching temperature coefficient is guaranteed less than 3ppm/°C. The resistors are extremely linear with voltage, resulting in a gain nonlinearity of less than 10ppm.
