Note 1: Absolute Maximium 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 supply rails. If the differential input voltage exceeds 1.4V, or if an
input is driven beyond the supply rails, the input current should be limited
to less than 10mA. This parameter is not tested; however it is guaranteed
by characterization.
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 LT1803C/LT1803I, LT1804C/LT1804I and LT1805C/LT1805I
are guaranteed functional over the temperature range of –40°C and 85°C.
Note 5: The LT1803C/LT1804C/LT1805C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1803C/LT1804C/LT1805C 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 LT1803I/LT1804I/LT1805I are guaranteed to meet specified perfor-
mance 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 LT1805; between the two amplifiers on the
LT1804.
Note 10: Full power bandwidth is based on slew rate:
FPBW = SR/2πV
