Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
The LT1797C is guaranteed to meet 0°C to 70°C specifications and may cause permanent damage to the device. Exposure to any Absolute is designed, characterized and expected to meet the extended temperature Maximum Rating condition for extended periods may affect device limits, but is not tested at –40°C and 85°C. The LT1797I is guaranteed to reliability and lifetime. meet specified performance from –40°C to 85°C.
Note 2:
A heat sink may be required to keep the junction temperature
Note 4:
This parameter is not 100% tested. below absolute maximum.
Note 5:
VS = 3V limit guaranteed by correlation to 5V tests.
Note 6:
Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP 1797fc 4 For more information www.linear.com/LT1797
