LT1991

Precision, 100µA

Gain Selectable Ampliﬁer

FEATURES

DESCRIPTION

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 resis-

tor 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 volt-

age 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 non-

linearity of less than 10ppm.

560kHz Gain Bandwidth Product

Rail-to-Rail Output

Space Saving 10-Lead MSOP and DFN Packages

APPLICATIONS

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

from –40°C to 125°C. The device is available in space

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

3mm DFN packages.
