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: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 3: V

Note 6: This specifi cation implies a typical input offset voltage of 5.7mV at
V
CM
= 18V and a maximum input offset voltage of 18mV at V
CM
= 18V.
Note 7: This parameter is not 100% tested.
Note 8: Specifi cations apply to 6-lead SOT-23 with shutdown.
Note 9: Full-power bandwidth is calculated from the slew rate.

Note 10: The LT1784C is guaranteed functional over the operating
temperature range –40°C to 85°C.
Note 11: The LT1784C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LT1784C 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. LT1784I is guaranteed to meet specifi ed
performance from –40°C to 85°C.
