Components
Function Description
1, 2
Cs
Provides power supply filtering and bypassing.
3, 4
Rsn
Works with Csn to stabilize the output stage from high frequency oscillations.
5, 6
Csn
Works with Rsn to stabilize the output stage from high frequency oscillations.
7
Cb
Provides filtering for the internally generated half-supply bias generator.
8, 9
Ci
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
Co
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
Ri
Voltage control - limits the voltage level to the amplifier’s input terminals.
