EXTERNAL COMPONENTS DESCRIPTION

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. Creunderates 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.
