TS4604 with IPAD for ESD immunity

Pop-&-click circuitry
Thanks to the internal negative supply the headphone and line driver outputs are referred to
ground without the need for bulky in-series capacitors. As a result, the pop created by these
bulky capacitors is eliminated. In addition, the TS4604 includes a pop-&-click circuitry that
suppresses any residual pop on the outputs, thus enabling the outputs to be virtually pop-&-
click-free.
6.12
Start-up phase
To further improve the pop-&-click performance, two important points must be taken into
account during the start-up phase.
Input capacitor
During the start up phase, as long as the AC input coupling capacitors are not fully charged,
we suggested to remain the EN_LD and En_HP and/or Ext_UVP pin low.
The constant time for an RC filter is given by:
We can consider that the input capacitor Cin will be charged at 95% of its maximum value
