Figure 64. TPA0103 Example Input MUX Circuit
Another advantage of using the MUX feature is setting the gain of the headphone channel to –1. This provides
the optimum distortion performance into the headphones where clear sound is more important.
mute and shutdown modes
The TPA0103 employs both a mute and 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 low during normal operation when the amplifier is in use. Pulling SHUTDOWN high
causes the outputs to mute and the amplifier to enter a low-current state, IDD = 5 A. SHUTDOWN should never
be left unconnected because amplifier operation would be unpredictable. Mute mode alone reduces IDD <1 mA.
