ELECTRICAL CHARACTERISTICS
The l denotes the specifi cations which apply over the full operating
temperature range of –40°C ≤ TA ≤ 125°C. VS = ±5V, VCM = 0V, VOUT = 0V, for the 6-lead part VPIN5 = V–, pulse power tested unless
otherwise specifi ed. (Note 4)
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: The LT1782C and LT1782I are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LT1782H is guaranteed
functional over the operating temperature range of –40°C to 125°C.
Note 4: The LT1782C is guaranteed to meet specifi ed performance from
0°C to 70°C. The LT1782C 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 LT1782I is guaranteed to meet
specifi ed performance from – 40°C to 85°C. The LT1782H is guaranteed to
meet specifi ed performance from –40°C to 125°C.
Note 5: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±5V or VS = ±9V tests.
Note 6: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±5V or VS = ±9V tests.
Note 7: Guaranteed by correlation to slew rate at VS = ±5V, and GBW at
VS = 3V and VS = ±5V tests.
Note 8: This specifi cation implies a typical input offset voltage of 1.8mV at
VCM = 18V and a maximum input offset voltage of 7.2mV at VCM = 18V.
Note 9: This parameter is not 100% tested.
Note 10: Specifi cations apply to 6-lead SOT-23 with shutdown.
Note 11: Full-power bandwidth is calculated for the slew rate.
FPBW = SR/2VP.
