Applications Information
Package Power Dissipation
Warning: Due to the high-output-current drive, this op
amp can exceed the absolute maximum power-dissi-
pation rating.
As a general rule, as long as the peak cur-
rent is less than or equal to 50mA, the maximum package
power dissipation will not be exceeded for any of the
package types offered. There are some exceptions to this
rule, however. The absolute maximum power-dissipation
rating of each package should always be verified using
the following equations. The following equation gives an
approximation of the package power dissipation:
P
V
IC DISS
RMS RMS
where: V
RMS
= the RMS voltage from V
CC
to V
OUT
when sourcing current
= the RMS voltage from V
OUT
to V
EE
when sinking current
I
RMS
= the RMS current flowing out of or into
the op amp and the load
θ
= the phase difference between the
voltage and the current. For resistive
loads, COS
θ
= 1.
For example, the circuit in Figure 1 has a package
power dissipation of 220mW.
Therefore, P
IC(DISS)
= V
RMS
I
RMS
COS
θ
= 220mW
Adding a coupling capacitor improves the package
power dissipation because there is no DC current to
the load, as shown in Figure 2.
Therefore, P
IC(DISS)
= V
RMS
I
RMS
COS
θ
= 45mW
The absolute maximum power-dissipation rating of the
package may be exceeded if the configuration in
Figure 1 is used with the MAX4335/MAX4336 amplifiers
at a high ambient temperature of 79
°
C (220.6mW/
°
C
plus a derating of 3.1mW/
°
C x 9
°
C = 247.9mW). Note
that the 247.9mW just exceeds the absolute maximum
power dissipation of 245mW for the 6-pin SC70 package.
