SHUTDOWN MODES
TPA0212
SLOS284B – NOVEMBER 1999 – REVISED NOVEMBER 2004
If it is desired to ac-couple the PC-BEEP input, the value of the coupling capacitor should be chosen to satisfy
Equation 14:
The PC-BEEP input can also be dc-coupled to avoid using this coupling capacitor. The pin normally sits at
midrail when no signal is present.
The TPA0212 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 should never be left unconnected
because amplifier operation would be unpredictable.
