ELECTRICAL CHARACTERISTICS The l denotes the speciﬁcations which apply over the full speciﬁed

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 LTC6087C/LTC6088C are guaranteed functional over the

operating temperature range of –40°C to 85°C. The LTC6087H/LTC6088H

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

to 125°C.

Note 4: The LTC6087C/LTC6088C are guaranteed to meet speciﬁed

performance from 0°C to 70°C. The LTC6087C/LTC6088C are designed,

characterized and expected to meet speciﬁed performance from –40°C to

125ºC but are not tested or QA sampled at these temperatures.

The LTC6087H/LTC6088H 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 LTC6087/LTC6088; 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.
