LT1991 - Precision, 100µA Gain Selectable Amplifier

The LT1991 combines a precision Operational Amplifier with eight precision resistors to form a one-chip solution for accurately amplifying voltages. Gains from -13 to 14 with a gain accuracy of 0.04% CAN be achiev 531 ed 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 50V maximum input offset voltage and a gain bandwidth product of 560kHz. The device operates from any supply voltage from 2.7V to 36V and draws only 100A 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 coefficent is guaranteed less than 3ppm/C. The resistors are extremely linear with voltage, resulting in a gain nonlinearity of less than 10ppm.
The LT1991 is fully specified at 5V and 15V supplies and from -40C to 85C. The device is available in space saving 10-lead MSOP and low profile (0.8mm) 3mm 3mm DFN packages.
