ELECTRICAL CHARACTERISTICS

meet specified performance from –40

°C to 85°C but is not tested or QA

sampled at these temperatures. The LT1806I is 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: Thermal resistance varies depending upon the amount of PC board

metal attached to Pin 4 of the device.

θJA is specified for a 2500mm2 test

board covered with 2 oz copper on both sides.

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 LT1806C/LT1806I are guaranteed functional over the

temperature range of –40

°C and 85°C.

Note 5: The LT1806C is guaranteed to meet specified performance from

°C to 70°C. The LT1806C is designed, characterized and expected to
