Figure 17. DAC Filters
The de-emphasis filters used in the TLV320AIC3007 can be programmed as described in the
data sheet, using this tab (
). Enter the coefficients for the de-emphasis filter
response desired. While on this tab, the de-emphasis response is shown on the Effect Filter Response
graph; however, note that this response is not included in graphs of other effect responses when on other
filter design tabs.

The digital audio input stream can be routed through the digital effects filter in the codec before routing to
the DAC to allow custom audio performance. The digital effects filter cannot operate on both the ADC or
DAC at the same time. The digital effects filter operation is discussed in
the DAC to allow custom audio performance. The digital effects filter cannot operate on both the ADC or
DAC at the same time. The digital effects filter operation is discussed in
