APPLICATION CIRCUIT
Single Power Supply (No Loudness and No Backup Circuit)
L-Ch Output
L-Ch Input
R-Ch Output
R-Ch Input
Rx
Cx
100
Note: Modifying the values of Rx and Cx affects the Oscillator Frequency of the IC. If the Fosc value is
big, then the volume control change is fast. Likewise, if the Fosc value is small, the volume control
change is slow. It is suggested that Rx= 33K, Cx = 2.2uF. The table for the Rx, Cx and Fosc values are
given below.
