ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range of –40°C < TA < 125°C, otherwise specications are at TA = 25°C. Split supply operation VS = ±15V, VCM = 0V
unless otherwise noted. (Note 4)

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 absolute maximum.
Note 3: The LT1716C/LT1716I are guaranteed functional over the operating
temperature range of –40°C to 85°C. The LT1716H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 4: The LT1716C is guaranteed to meet specied performance from
0°C to 70°C. The LT1716C is designed, characterized and expected to meet
performance from –40°C to 85° but is not tested or QA sampled at the
temperatures. The LT1716I is guaranteed to meet specied performance
from –40°C to 85°C. The LT1716H is guaranteed to meet specied
performance from –40°C to 125°C.
Note 5: This parameter is not 100% tested.
Note 6: Typical input offset voltage of 500μV at VCM = 44V above V– and a
maximum input offset voltage of 4mV at VCM = 44V above V–.
Note 7: If one input is within this input range, the other input can go 5V
below V– and the output will be valid.
