TLV320AIC3007EVM-K

This user's guide describes the characteristics, operation, and use of the TLV320AIC3007EVM-K. Thisevaluation module (EVM) allows the user to evaluate the TLV320AIC3007 audio codec. TheTLV320AIC3007 is a complete 2-channel audio codec with an integrated Class-D speaker amplifier. It alsohas many inputs and outputs, extensive audio routing, mixing, and effects capabilities. A complete circuitdescription, schematic diagram, and bill of materials are included. Note that the TLV320AIC3007 onlyuses the I

C™ bus for register control. Any references to the SPI control bus in this document is due tothe presence of this interface on the USB-MODEVM motherboard.

Note: For a quick start, go directly to Section 3.1 Software Installation, followed by Section 3.2EVM Connections, and then to Section 4.1 Quick Start Tabs.
