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.

Note 10: Thermal resistance (

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
