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/2
