Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The inputs are protected by internal resistors and back-to-back
diodes. If the differential input voltage exceeds ±0.7V, the input current
should be limited externally to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4: The LT1881C/LT1882C and LT1881I/LT1882I are guaranteed
functional over the operating temperature range of – 40°C to 85°C.
The LT1882H is guaranteed functional over the operating temperature
range –40°C to 125°C. The LT1882MP is guaranteed functional over the
operating temperature range –55°C to 125°C.
Note 5: The LT1881C/LT1882C are guaranteed to meet specifi ed
performance from 0°C to 70°C. The LT1881C/LT1882C are designed,
characterized and expected to meet specifi ed performance from – 40°C
to 85°C but are not tested or QA sampled at these temperatures. The
LT1881I/LT1882I are guaranteed to meet specifi ed performance from
– 40°C to 85°C. The LT1882H is guaranteed to meet specifi ed performance
from –40°C to 125°C. The LT1882MP is guaranteed to meet specifi ed
performance from –55°C to 125°C.

Note 6: This parameter is not 100% tested.
Note 7: Matching parameters are the difference between amplifi ers
A and B in the LT1881; and between amplifi ers A and D and B and C in the
LT1882.
Note 8: This parameter is the difference between the two noninverting
input bias currents.
Note 9: ΔCMRR and ΔPSRR are defi ned as follows: CMRR and PSRR are
measured in μV/V on each amplifi er. The difference is calculated in μV/V
and then converted to dB.
Note 10: Full power bandwidth is calculated from the slew rate: FPBW =
SR/2πV
