ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the specied
temperature range, otherwise specications are at TA = 25°C. VS = ±5V, VCM = 0V, VOUT = 0V, for the 6-lead part VPIN5 = V–,
pulse power tested unless otherwise specied.

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: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±5V or VS = ±9V tests.
Note 4: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±5V or VS = ±9V tests.
Note 5: Guaranteed by correlation to slew rate at VS = ±5V, and GBW at
VS = 5V and VS = ±5V tests.
Note 6: This specication implies a typical input offset voltage of 5.7mV at
VCM = 18V and a maximum input offset voltage of 18mV at VCM = 18V.
Note 7: This parameter is not 100% tested.
Note 8: Specications apply to 6-lead SOT-23 with shutdown.
Note 9: Full-power bandwidth is calculated from the slew rate.
FPBW = SR/2πVP.
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 specied performance from
0°C to 70°C. The LT1784C is designed, characterized and expected to
meet specied performance from –40°C to 85°C but is not tested or QA
sampled at these temperatures. LT1784I is guaranteed to meet specied
performance from –40°C to 85°C.
