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. If the differential

input voltage exceeds 1.4V, the input current should be limited to less than

10mA. It is not 100% tested.

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.

metal connected to the package. The specified values are for short

traces connected to the leads. If desired, the thermal resistance can be

substantially reduced by connecting Pin 4 of the SO-8 and MS8, Pin 11 of

the SO-14 or the underside metal of the DD package to a larger metal area
