Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The inputs are protected by back-to-back diodes. If the differential

input voltage exceeds 10V, see Application Information, the input current

should be limited to less than 10mA.

Note 3: A heat sink may be required to keep the junction temperature

below absolute maximum ratings.

Note 4: The LT1880C and LT1880I are guaranteed functional over the

operating temperature range of –40

°C to 85°C.

Note 5: The LT1880C is guaranteed to meet specified performance from

0

°C to 70°C and is designed, characterized and expected to meet specified

performance from –40

°C to 85°C but is not tested or QA sampled at these

temperatures. The LT1880I is guaranteed to meet specified performance

from –40

°C to 85°C.

Note 6: This parameter is not 100% tested.

Note 7: Full power bandwidth is calculated from the slew rate.

FPBW = SR/(2
