60812f

The ● denotes the speciﬁcations which apply over the full operating

temperature range, otherwise speciﬁcations are at TA = 25°C. Test conditions are V+ = 5V, V– = 0V, VCM = 0.5V unless otherwise noted.

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 VOS 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.

Note 6: IB guaranteed by the VS = 5V test.

Note 7: Current noise is calculated from In = √2qIB, where q = 1.6 • 10–19

coulomb.

Note 8: VOS drift is guaranteed by the VS = 3V test.
