Figure 4. Circuit for External Components Description
EXTERNAL COMPONENTS DESCRIPTION
Components Function Description
1, 2 C
S
Provides power supply filtering and bypassing.
3, 4 R
SN
Works with C
SN
to stabilize the output stage from high frequency oscillations.
5, 6 C
SN
Works with R
SN
to stabilize the output stage from high frequency oscillations.
7 C
b
Provides filtering for the internally generated half-supply bias generator.
8, 9 C
i
Input AC coupling capacitor which blocks DC voltage at the amplifier's input terminals. Also creates a high pass
filter with fc=1/(2 • π • Rin • Cin).
10, 11 C
o
Output AC coupling capacitor which blocks DC voltage at the amplifier's output terminal. Creates a high pass filter
with fc=1/(2 • π • Rout • Cout).
12, 13 R
i
Voltage control - limits the voltage level allowed to the amplifier's input terminals.
14 R
m
Works with C
m
to provide mute function timing.
15 C
m
Works with R
m
to provide mute function timing.
