SHUTDOWN MODES
TPA0142
SLOS248E – JUNE 1999 – REVISED SEPTEMBER 2004
The TPA0142 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.
