8 Application Information

Package Power Dissipation

Caution: Due to the high output current drive, this op amp can exceed the absolute maximum power-dissipation rat-

ing. Normally, when peak current is less than or equal to 40mA the maximum package power dissipation is

not exceeded for any of the package types offered.

The absolute maximum power-dissipation rating of each package should always be verified. (EQ 1) gives an approxi-

mation of the package power dissipation:

For the circuit shown in Figure 21:

Ω) + (1.0V/32Ω)/

Therefore, for the circuit in Figure 21 the package power dissipation can be calculated as:

Adding a coupling capacitor improves the package power dissipation because there is no DC current to the load, as

shown in Figure 22 on page 10.
