APPLICATION INFORMATION
FADE operation (continued)
In the fade-off mode, the amplifier stores the gain value prior to starting the shutdown sequence. The output
of the amplifier immediately drops to V
DD
/2 and the bypass capacitor begins a smooth discharge to ground.
When shutdown is released, the bypass capacitor charges up to V
DD
/2 and the channel gain returns
immediately to the value stored in memory. Figure 31 below is a waveform captured at the output during the
shutdown sequence when the part is in the fade-off mode. The gain is set to the highest level, and the output
is at V
DD
when the amplifier is shut down.
The power-up sequence is different from the shutdown sequence and the voltage on the FADE pin does not
change the power-up sequence. Upon a power-up condition, the TPA6011A4 begins in the lowest gain setting
and steps up 2 dB every 2 clock cycles until the final value is reached as determined by the dc voltage applied
to the VOLUME, SEDIFF, and SEMAX pins.
