4. Countermeasure for shock noise of the AN7198Z (continued)
3) Muting on/off (Pin7 low: Muting state, high: Operating state) (continued)
(2) Attack and recovery time of muting on/off is determined by the external CR time constant of pin 7.
(3) There is afraid of shock noise when time constant is set to 10 ms or less.
(Since output DC voltage is changed approx. 50 mV by muting on/off.)
