5) Gain settings for the mute detection circuit
The gain settings for the mute detection circuit are shown below. The reference voltage of the comparator circuit is set
at V
As an example, when V
detection level during playback is obtained as follows:
a. The reference voltage of the comparator circuit is V =
V
input of 0.3 / 2V
Audio ICs
CC
/ 30 = 0.3V, therefore, the circuit will operate at an AC
CC
/ 30.
rms
= *13.5dBV or more.
CC
= 9V and f = 5kHz, the mute
b. From the above chart, the gain at 5kHz during play-
back is 80dB.
c. Therefore, the output / input level of mute detection is
*13.5 * 80 = *93.5dBV.
