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 allowed to the amplifier’s input terminals.
