TLV320AIC3109EVM Software
The TLV320AIC3109-Q1 audio codec is a mono version of the TLV320AIC3104 device, so the
configuration and control of the TLV320AIC3109EVM is made using the TLV320AIC3104EVM software.
Some features of the TLV320AIC3104EVM GUI will not be available for the TLV320AIC3109EVM,
detailed information about these features are included in the following sections. As the GUI is adapted for
the TLV320AIC3104 device, the names for the signal and internal channels are not the same in some
cases for the TLV320AIC3109. In general, the single channel of the TLV320AIC3109-Q1 corresponds to
the left channel of the TLV320AIC3104, being the only exception the single headphone output, that
corresponds to the right headphone output of the TLV320AIC3104.
indicates the relationship
between the GUI and TLV320AIC3109-Q1 signal and internal block names.
