For example, the circuit in Figure 1 has a package power
dissipation of 196mW:

where:
VDC = the DC component of the output voltage.
IDC = the DC component of the output current.
VPEAK = the highest positive excursion of the AC compo-
nent of the output voltage.
IPEAK = the highest positive excursion of the AC compo-
nent of the output current.
Therefore:

Adding a coupling capacitor improves the package power
dissipation because there is no DC current to the load, as
shown in Figure 2:

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-supply,
stereo headphone driver. The circuit shown in Figure 2 can
deliver 60mW per channel with 1% distortion from a single
5V supply.
The input capacitor (CIN), in conjunction with RIN, forms a
highpass filter that removes the DC bias from the incom-
ing signal. The -3dB point of the highpass filter is given by
3dB
