Analog
Voice (Voltage) Input
,
Channel 2
Requires a coupling capacitor >39 nF to the SLIC.
Reference Voltage
Must connect to a 220 nF cap. to ground.
Analog Supply Reference Voltage
+5 V (100 nF blocking capacitor required).
Analog Voice (Voltage) Input, Channel 3
Requires a coupling capacitor >39 nF to the SLIC.
Analog Ground, Channel 3
Not internally connected to GNDD or GNDA1,2,4.
Analog Voice (Voltage) Output, Channel 3
Requires a coupling capacitor to the SLIC. The capacitor
value depends on the SLIC
