Application without volume control
If pins 6, 7 and 8 are hardwired together the device operates with the volume control setting at maximum.
When the supply voltage is connected and the device is switched from standby to mute or operating for the first time then
the gain is ramped up from −20 dB to +20 dB. This takes approximately 5 s.
This maximum gain setting is maintained until the supply voltage drops below the minimum value.
