No. 873- 6/13
Setting of C112 (Capacitance between pin 12 and ground)
C112 influences S/N and muting attenuation. S/N is improved 0.5 to 2.0dB by changing C112 from 1μF to 100μF.
Muting attenuation becomes as shown in Mute (att) – fm (next page) characteristic. This phenomenon occurs because
the output at pin 7 appears at pin 6 through pin 10 and capacitance C110 between pin 7 and ground also exerts
influence. The relation between muting attenuation and C110 is such that if C110 = 2.2μF and C112 = 220μF,
attenuation at modulation frequency 100Hz becomes
80dB.
