LT1783
ELECTRICAL CHARACTERISTICS
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 5: V = 5V limits are guaranteed by correlation to V = 3V and
S

Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 7: Guaranteed by correlation to slew rate at V = 5V, and GBW at
S
V = 3V and V = 5V tests.

Note 3: The LT1783C and LT1873I are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LT1783H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 8: This specification implies a typical input offset voltage of 1.8mV at
= 18V and a maximum input offset voltage of 7.2mV at V = 18V.
Note 9: This parameter is not 100% tested.

Note 4: The LT1783C is guaranteed to meet specified performance from
0°C to 70°C. The LT1783C 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 LT1783I is guaranteed to meet
specified performance from –40°C to 85°C. The LT1783H is guaranteed to
meet specified performance from –40°C to 125°C.
Note 10: Specifications apply to 6-lead SOT-23 with shutdown.
Note 11: Full-power bandwidth is calculated from the slew rate:
FPBW = SR/2πV .
