SBAS174C – FEBRUARY 2002 – REVISED FEBRUARY 2007
Single-channel signals within stereo-audio data input are output to both I
OUT
L and I
OUT
R as differential outputs.
Selection of channels to output is available with the CHSL bit in register 20. Applications, such as monaural
operation,are useful for high-end audio applications to provide over 120 dB for dynamic range. A typical MONO
mode application is shown in Figure 47 .
