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. If the differential
input voltage exceeds 1.4V, 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 LT1801C/LT1801I and LT1802C/LT1802I are guaranteed
functional over the temperature range of – 40
°C to 85°C.
Note 5: The LT1801C/LT1802C are guaranteed to meet specified
performance from 0
°C to 70°C. The LT1801C/LT1802C are designed,
characterized and expected to meet specified performance from
–40
°C to 85°C but are not tested or QA sampled at these temperatures.
The LT1801I/LT1802I are 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.
Note 9: Matching parameters are the difference between amplifiers A
and D and between B and C on the LT1802; between the two amplifiers
on the LT1801.
