Philips Semiconductors Preliminary specification Power amplifier with load detection and auto BTL/SE selection The presence of the load is measured after the transition between standby and mute. The IC will determine if there is an acceptable load on both outputs (OUT2 and OUT4). If both outputs are unloaded, the IC will switch to a 2 speaker mode of operation (BTL mode), unless it is overruled.
