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 specifi ed
performance from 0°C to 70°C. The LTC6084C/LTC6085C are designed,
characterized and expected to meet specifi ed performance from –40°C
to 85°C but are not tested or QA sampled at these temperatures. The
LTC6084H/LTC6085H are guaranteed to meet specifi ed 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 specifi cation is limited by high speed automated test
capability. See Typical Performance Characteristic curves for actual
performance.
Note 8: Current noise is calculated from i
n
= √2qI
B
, where q = 1.6 • 10
