3. Unless otherwise noted, the following conditions apply: ±VS = ±15V, T C =25°C.
4. +VS and -Vs denote the positive and negative rail respectively. VSS denotes total rail-to-rail supply.
5. Rating applies when power dissipation is equal in each of the amplifiers. Power and thermal ratings
are based on two separate dual monolithic power op-amps on one integrated copper heatslug.
Amplifiers A and B are combined on one monolithic die while amplifiers C and D are on the other.
6.
If
-Vs
is
disconnected
before
+Vs,
a
diode
between
-V
s
and
ground
is
recommended
to
avoid
dam-
age.
7. Rating applies when the heatslug of the DK package is soldered to a minimum of 1 square inch foil
area of a printed circuit board.
