Function Description
Provides power supply filtering and bypassing.
Works with Csn to stabilize the output stage from high frequency oscillations.
Works with Rsn to stabilize the output stage from high frequency oscillations.
Provides filtering for the internally generated half-supply bias generator.
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).
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).
Voltage control - limits the voltage level to the amplifier’s input terminals.
