TIMING-CHART AND ACTION TIME AT MUTE
Test conditions: V

The following values are typical characteristics, accordingly they are not guaranteed values.
[Attack action start (mute on)]
When the mute action was attacked, the charge current starts inflow, then the voltage at the pin for the capacitor rises
up to 0.6 V. The rise time to 0.6 V is the following formula.
The voltage of Pin 4 functions to 0.6 V by the upper limit circuit. In the estimate, when the pin of capacitor is 0.15 V
and between 0.16 V, the attenuation value is about 90% in the final attenuation value.
So it is the following calculation and timing chart.
[Release action start (mute off)]
When the mute action was released, the discharge current starts outflow, then the voltage at the pin for the capacitor
drops up to 10 mV. The drop time to 10 mV is the following formula.

In the estimate, when the pin of the capacitor is 0.16 V and between 0.15 V, the attenuation value is restored about
90% against the input value.
So it is the following calculation and timing chart.
