This user's guide describes the characteristics, operation, and use of the TLV320AIC34EVM-K. This
evaluation module (EVM) allows the user to evaluate the TLV320AIC34 audio codec. The TLV320AIC34 is
a complete 4-channel audio codec with several inputs and outputs, extensive audio routing, mixing and
effects capabilities. A complete circuit description, schematic diagram and bill of materials are also
included. Note that the TLV320AIC34 only uses the I
2
C bus for register control. Any references to the SPI
control bus in this document is due to the presence of this interface on the USB-MODEVM motherboard.
