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: A heat sink may be required to keep the junction temperature
below the absolute maximum. This depends on the power supply voltage
and how many amplifiers are shorted.
Note 3: The LTC6081C/LTC6082C and LTC6081I/LTC6082I are guaranteed
functional over the operating temperature range of –40°C to 85°C.
The LTC6081H/LTC6082H are guaranteed functional over the operating
temperature range of –40°C to 125°C.
Note 4: The LTC6081C/LTC6082C are guaranteed to meet specified
performance from 0°C to 70°C. The LTC6081C/LTC6082C are designed,

characterized and expected to meet specified performance from –40°C
to 85°C but are not tested or QA sampled at these temperatures. The
LTC6081I/LTC6082I are guaranteed to meet specified performance from
–40°C to 85°C. The LTC6081H/LTC6082H are guaranteed to meet specified
performance from –40°C to 125°C.
Note 5: Input offset drift is computed from the limits of the V

test
divided by the temperature range. This is a conservative estimate of worst
case drift. Consult the Typical Performance Characteristics section for
more information on input offset drift.
