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.
