Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
ESD (Electrostatic Discharge) sensitive device. ESD protection may cause permanent damage to the device. Exposure to any Absolute devices are used extensively internal to the LTC6084/LTC6085; however, Maximum Rating condition for extended periods may affect device high electrostatic discharge can damage or degrade the device. Use proper reliability and lifetime. ESD handling precautions.
Note 2:
A heat sink may be required to keep the junction temperature
Note 6:
This parameter is not 100% tested. below the absolute maximum. This depends on the power supply voltage
Note 7:
This specifi cation is limited by high speed automated test and the total output current. capability. See Typical Performance Characteristic curves for actual
Note 3:
The LTC6084C/LTC6085C are guaranteed functional over the performance. operating temperature range of –40°C to 85°C. The LTC6084H/LTC6085H
Note 8:
Current noise is calculated from in = √2qIB, where q = 1.6 • 10–19 are guaranteed functional over the operating temperature range of –40°C coulombs. 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. 60845fa 5
