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: ESD (Electrostatic Discharge) sensitive devices. Extensive use of
ESD protection devices are used internal to the LT6100, however, high
electrostatic discharge can damage or degrade the device. Use proper ESD
handling precautions.
Note 3: A heat sink may be required
to keep the junction temperature
below absolute maximum ratings.
Note 4:
The LT6100C/LT6100I are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LT6100H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 5: The LT6100C is guaranteed to meet specified performance from
0°C to 70°C. The LT6100C is designed, characterized and expected to
meet specified performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures. The LT6100I is guaranteed to meet
specified performance from –40°C to 85°C. The LT6100H is guaranteed to
meet specified performance from –40°C to 125°C.
Note 6: This parameter is not 100% tested.
Note 7: Gain error for A
V
= 12.5, 25V/V is guaranteed by the other gain
error tests.
Note 8: Slew rate is measured on the output between 3.5V and 13.5V.
