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: The inputs are protected by back-to-back diodes and by ESD
diodes to the supply rails. If the differential input voltage exceeds 1.4V or
either input goes outside the rails, the input current should be limited to
less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefi nitely.
Note 4: The LT1800C/LT1800I are guaranteed functional over the
temperature range of –40°C to 85°C.
Note 5: The LT1800C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LT1800C is designed, characterized and expected to
meet specifi ed performance from –40°C to 85°C but is not tested or
QA sampled at these temperatures. The LT1800I is guaranteed to meet
specifi ed performance from –40°C to 85°C.
Note 6: Minimum supply voltage is guaranteed by power supply rejection
ratio test.
Note 7: Output voltage swings are measured between the output and
power supply rails.
Note 8: This parameter is not 100% tested.
