ELECTRICAL CHARACTERISTICS
The l denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T
A
= 25°C. V
S
= ± 15V; V
CM
= 0V unless otherwise noted. (Note 5)
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 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 specifi ed performance from
0°C to 70°C and is designed, characterized and expected to meet specifi ed
performance from –40°C to 85°C but is not tested or QA sampled at these
temperatures. The LT1880I is guaranteed to meet specifi ed 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.
