Note 1:
Absolute Maximum Ratings are those beyond which the life of the
device may be impaired.
Note 2:
The P3/M3 and P9/M9 inputs should not be taken more than 0.2V
beyond the supply rails. The P1/M1 inputs can withstand
±
60V if P9/M9
are grounded and V
S
=
±
15V (see Applications Information section about
“High Voltage CM Difference Amplifiers”).
Note 3:
A heat sink may be required to keep the junction temperature
below absolute maximum ratings.
Note 4:
Both the LT1991C and LT1991I are guaranteed functional over the
–40
°
C to 85
°
C temperature range.
Note 5:
The LT1991C is guaranteed to meet the specified performance
from 0
°
C to 70
°
C and is designed, characterized and expected to meet
specified performance from –40
°
C to 85
°
C but is not tested or QA
sampled at these temperatures. The LT1991I is guaranteed to meet
specified performance from –40
°
C to 85
°
C.
Note 6:
This parameter is not 100% tested.
Note 7:
Input voltage range is guaranteed by the CMRR test at V
S
=
±
15V.
For the other voltages, this parameter is guaranteed by design and through
correlation with the
±
15V test. See the Applications Information section to
determine the valid input voltage range under various operating
conditions.
Note 8:
Offset voltage, offset voltage drift and PSRR are defined as
referred to the internal op amp. You can calculate output offset as follows.

Note 9:
Applies to resistors that are connected to the inverting inputs.
Resistor matching is not tested directly, but is guaranteed by the gain
error test.
Note 10:
Input impedence is tested by a combination of direct
measurements and correlation to the CMRR and gain error tests.
