    APPLICATION SUGGESTION

    STAND-BY AND MUTE FUNCTIONS


    (A) Microprocessor Application

    In order to avoid annoying "Pop-Noise" during Turn-On/Off transients, it is necessary to guarantee the right Stby and mute signals sequence. It is quite simple to obtain this function using a microprocessor (Fig. 1 and 2). At first St-by signal (from µP) goes high and the voltage across the St-by terminal (Pin 7) starts to increase exponentially. The external RC network is intended to turn-on slowly the biasing circuits of the amplifier, this to avoid "POP" and "CLICK" on the outputs.

    When this voltage reaches the St-by threshold level, the amplifier is switched-on and the external capacitors in series to the input terminals (C3, C53) start to charge.

    It's necessary to mantain the mute signal low until the capacitors are fully charged, this to avoid that the device goes in play mode causing a loud "Pop Noise" on the speakers.

    A delay of 100-200ms between St-by and mute signals is suitable for a proper operation.
