Applications Information (Continued)
TABLE 3. These are the functions selected by the jumpers on the recommended PC board. (Continued)
Class AB
Shorting activates the headphone amplifier and deactivates the Class D amplifier. Class D and
HP jack jumpers are open
Class D
Shorting activates the Class D amplifier and deactivates the headphone amplifier. Class AB and
HP jack jumpers are open
HP Jack
Shorting allows the act of plugging in headphones to activate the headphone amplifier and
deactivate the Class D amplifier. Removing headphones restores Class D amplifier operation and
deactivates the headphone amplifier. Class AB and Class D jumpers are open. (Requires the
use of a headphone jack like that shown in Figure 1.)

FIGURE 2. At power-up, the LP3740 forces the LM4663 into shutdown, which prevents abnormal quiescent current
flow through the amplifier. Once V
CC rises above 4V and after a 200ms delay set by C1, normal amplifier operation is
restored.
