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
