APPLICATIONS INFORMATION

The MC33076 dual operational amplifier is available in the

standard 8–pin plastic dual–in–line (DIP) and surface mount

packages, and also in a 16–pin batwing power package. To

enhance the power dissipation capability of the power

package, Pins 4, 5, 12, and 13 are tied together on the

leadframe, giving it an ambient thermal resistance of 52°C/W

typically, in still air. The junction–to–ambient thermal

resistance (RθJA) can be decreased further by using a copper

padb on the printed circuit board (as shown in Figure 26) to

draw the heat away from the package. Care must be taken

not to exceed the maximum junction temperature or damage

to the device may occur.
