This user's guide describes the characteristics, operation, and use of the TLV320AIC3107EVM-K. This
evaluation module (EVM) allows the user to evaluate the TLV320AIC3107 audio codec. The
TLV320AIC3107 is a complete 2-channel audio codec with an integrated Class-D speaker amplifier. It also
has many inputs and outputs, extensive audio routing, mixing, and effects capabilities. A complete circuit
description, schematic diagram, and bill of materials are included. Note that the TLV320AIC3107 only
2
uses the I
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.
