LT1794

ELECTRICAL CHARACTERISTICS

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 LT1794C is guaranteed to meet specified performance from

0

°C to 70°C and is designed, characterized and expected to meet these

extended temperature limits, but is not tested at – 40

°C and 85°C. The

LT1794I 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. 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 7: Slew rate is measured at

±5V on a ±10V output signal while

operating on

±15V supplies and ±1V on a ±3V output signal while

operating on

±5V supplies.
