Other Parts Discussed in Thread: TLV320AIC23B

Hi,

I am using DSK5510 fixed-point board. It has TLV320AIC23b audio codec. I am trying to generate a sine wave with DC offset (for modulation) but I see its AC part only when I view sine wave on oscilloscope. Is AIC23b AC coupled?

Thanks,

Abhishek Seth.

Yes, the audio path is AC coupled. The schematics for the DSK5510 is available in the Technical Reference Manual for the board available on Spectrum Digital's support website.

Hi,

Thanks for you reply. I need to ask that is there any way to configure it in DC coupling mode? Are all DACs AC coupled?
