Description

The LT^®1991 combines a precision operational amplifi er 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 achieved using no external components. The device is particularly well suited for use as a difference amplifi er, where the excellent resistor matching results in a common mode rejection ratio of greater than 75dB.

The LT1991 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 coeffi cent 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 specifi ed at 5V and ±15V supplies and from 40°C to 125°C. The device is available in space saving 10-lead MSOP and low profi le (0.8mm) 3mm * 3mm DFN packages.
