For example, the circuit in Figure 1 has a package
power dissipation of 196mW:
where:
V
DC
= the DC component of the output voltage.
I
DC
= the DC component of the output current.
V
PEAK
= the highest positive excursion of the AC com-
ponent of the output voltage.
I
PEAK
= the highest positive excursion of the AC com-
ponent of the output current.
Therefore:
P
IC(DISS)
= V

I

θ
= 196mW
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
= 15.6mW
If the configuration in Figure 1 were used with all four of
the MAX4234 amplifiers, the absolute maximum power-
dissipation rating of this package would be exceeded
(see the
Absolute Maximum Ratings
section).
60mW Single-Supply Stereo
Headphone Driver
Two MAX4230/MAX4231s can be used as a single-sup-
ply, stereo headphone driver. The circuit shown in
Figure 2 can deliver 60mW per channel with 1% distor-
tion from a single 5V supply.
The input capacitor (C
IN
), in conjunction with R
IN
, forms
a highpass filter that removes the DC bias from the
incoming signal. The -3dB point of the highpass filter is
given by:
