Analog Voice (Voltage) Input, Channel 1
Requires a coupling capacitor >39 nF to the SLIC.
Analog Ground, Channel 1
Not internally connected to GNDD or GNDA2,3,4.
Analog Voice (Voltage) Output, Channel 1
Requires a coupling capacitor to the SLIC. The capacitor
value depends on the SLIC
’
s input impedance.

5.1 Analog Interface
)
Analog Supply Voltage
,
Channels 1 and 2
+5 V (100 nF blocking capacitor required).
Analog Voice (Voltage) Output, Channel 2
Requires a coupling capacitor to the SLIC. The capacitor
value depends on the SLIC
’
s input impedance.
