The

l 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 the total output current.

Note 3: The LTC6084C/LTC6085C are guaranteed functional over the

operating temperature range of –40°C to 85°C. The LTC6084H/LTC6085H

are guaranteed functional over the operating temperature range of –40°C

to 125°C.

Note 4: The LTC6084C/LTC6085C are guaranteed to meet speciﬁed

performance from 0°C to 70°C. The LTC6084C/LTC6085C 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

LTC6084H/LTC6085H are guaranteed to meet speciﬁed performance from

–40°C to 125°C.

Note 5: ESD (Electrostatic Discharge) sensitive device. ESD protection

devices are used extensively internal to the LTC6084/LTC6085; however,

high electrostatic discharge can damage or degrade the device. Use proper

ESD handling precautions.

Note 6: This parameter is not 100% tested.

Note 7: This speciﬁcation is limited by high speed automated test

capability. See Typical Performance Characteristic curves for actual

performance.

Note 8: Current noise is calculated from in = √2qIB, where q = 1.6 • 10–19

coulombs.
