... This startup operation is shown in figure 5. SHUTDOWN At Shutdown, The PA4401 detects a “power fail” condition and the control switches are turned off, opening the connection between INx and OUTx providing a discharge path through an internal 100KΩ resistor for the bypass capacitor. The time constant of the internal resistor and by-pass capacitor, allows for a slow discharge, which will prevent any audible “ ...
