Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current should be limited to less than
10mA.
Note 3:
A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4:
Thermal resistance varies depending upon the amount of PC board
metal attached to the device.

test board
covered with 2 oz copper on both sides.
Note 5:
Input offset voltage is exclusive of warm-up drift.
Note 6:
Slew rate is measured between
±
2V on a
±
4V output with
±
6V
supplies, and between
±
1V on a
±
1.5V output with
±
2.5V supplies.
Note 7:
Full power bandwidth is calculated from the slew rate:
FPBW = SR/2
π
V
P
.
Note 8:
This parameter is not 100% tested.
Note 9:
The LT1886C is guaranteed to meet specified performance from 0
°
C
to 70
°
C. The LT1886C 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. For guaranteed I-grade parts, consult the factory.
Note 10:
The LT1886C is guaranteed functional over the operating temperature
range of –40
°
C to 85
°
