LT1991

Precision, 100µA

Gain Selectable Amplifier

FEATURES

DESCRIPTIO

The LT^®1991 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 achieved using no

externalcomponents.Thedeviceisparticularlywellsuited

for use as a difference amplifier, where the excellent

resistor matching results in a common mode rejection

ratio of greater than 75dB.

Pin Configurable as a Difference Amplifier,

Inverting and Noninverting Amplifier

■

Difference Amplifier

Gain Range 1 to 13

CMRR >75dB

■

Noninverting Amplifier

Gain Range 0.07 to 14

■

Inverting Amplifier

Gain Range –0.08 to –13

The amplifier features a 50µV maximum input offset

voltage and a gain bandwidth product of 560kHz. The

device operates from any supply voltage from 2.7V to 36V

and draws only 100µA supply current on a 5V supply. The

output swings to within 40mV of either supply rail.

■

Gain Error <0.04%

■

Gain Drift < 3ppm/°C

■

Wide Supply Range: Single 2.7V to Split ±18V

■

Micropower: 100µA Supply Current

■

Precision: 50µV Maximum Input Offset Voltage

■

The resistors have excellent matching, 0.04% over tem-

peratureforthe450kresistors. Thematchingtemperature

coefficent is guaranteed less than 3ppm/°C. The resistors

are extremely linear with voltage, resulting in a gain

nonlinearity of less than 10ppm.

APPLICATIO S

The LT1991 is fully specified at 5V and ±15V supplies and

from –40°C to 85°C. The device is available in space

saving 10-lead MSOP and low profile (0.8mm) 3mm ×

3mm DFN packages.
