MAX4366/MAX4367/MAX4368
The effective gains of the MAX4367 and MAX4368 are
AVD = 2V/V and AVD = 3V/V respectively. Substituting 2
x VOUT(P-P) for VOUT(P-P) into the following equations
yields four times the output power due to doubling of
the output voltage.
Since the differential outputs are biased at midsupply,
there is no net DC voltage across the load. This elimi-
nates the need for DC-blocking capacitors required for
single-ended amplifiers. These capacitors can be
large, expensive, consume board space, and degrade
low-frequency performance.
Single-Ended Configuration
The MAX4366/MAX4367/MAX4368 can be used as sin-
gle-ended amplifiers (Figure 2). The gain of the device
in single-ended mode is 1/2 the gain in BTL configura-
tion and the output power is reduced by a factor of 4.
The single-ended gains of the MAX4367 and MAX4368
are 1V/V and 1.5V/V, respectively. Set the MAX4366
gain according to the
Gain-Setting Resistors section.
In single-ended mode, the load must be capacitively
coupled to the device output to block the half-supply
DC voltage from the load (see
Output Coupling
Capacitor section). Leave the unused output floating.
Power Dissipation
Under normal operating conditions, linear power ampli-
fiers like the MAX4366/MAX4367/MAX4368 can dissi-
pate a significant amount of power. The maximum
power dissipation for each package is given in the
Absolute Maximum Ratings section under Continuous
Power Dissipation or can be calculated by the following
equation:
where TJ(MAX) is +150°C and TA is the reciprocal of the
derating factor in °C/W as specified in the
