Note 2 :
This circuitry is intended for applications where
the CS4245 connects directly to an unbalanced
output of the design . For internal routing
applications please see the DAC Analog Output
Characteristics section for loading limitations .
Note 1: Resistors are required for I²C control
port operation
For best response to Fs/2 :
