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 6
: R
BIAS
is connected between V
+
and the SHDN pin.
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.
