Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Applies to short circuits to ground only. A short circuit between
the output and either supply may permanently damage the part when
operated on supplies greater than ±10V.
Note 3: The LT1739C is guaranteed to meet specified performance from
0°C to 85°C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at – 40°C. The LT1739I is
guaranteed to meet the extended temperature limits.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to the device and rate of air flow over the device. If the
maximum dissipation of the package is exceeded, the device will go into
thermal shutdown and be protected.
Note 5: Guaranteed by the CMRR tests.
Note 6: RBIAS is connected between V + and the SHDN pin, with the
SHDNREF pin grounded.
Note 7: Slew rate is measured at ±5V on a ±10V output signal while
operating on ±12V supplies and ±1V on a ±3V output signal while
operating on ±5V supplies.
Note 8: This parameter of the LT1739CUE/LT1739IUE is 100% tested at
room temperature, but is not tested at –40°C, 0°C or 85°C.
