SHUTDOWN MODES
TPA0152
SLOS246F – JUNE 1999 – REVISED SEPTEMBER 2004
The PC-BEEP input can also be dc-coupled to avoid using this coupling capacitor. The pin normally rests at
midrail when no signal is present.
Figure 39. TPA0152 Example Input MUX Circuit
The input MUX provides the user with a means to select from two different audio sources. In BTL mode, the
LINE input is selected. In SE mode, the HP inputs are selected. RLINEIN and LLINEIN must be AC-grounded in
SE mode.
The TPA0152 employs a shutdown mode of operation designed to reduce supply current (IDD) to the absolute
minimum level during periods of nonuse for battery-power conservation. The SHUTDOWN input terminal should
be held high during normal operation when the amplifier is in use. Pulling SHUTDOWN low causes the outputs to
mute and the amplifier to enter a low-current state, IDD = 150 A. SHUTDOWN must not be left unconnected
because amplifier operation would be unpredictable.
