Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
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
indefinitely.
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 specified performance from
0
°C to 70°C. The LT1800C 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 LT1800I is guaranteed to meet
specified 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.
