The TLV320AIC34EVM is in Texas Instruments' modular EVM form factor, which allows direct evaluation
of the device performance and operating characteristics, and eases software development and system
prototyping. This EVM is compatible with the 5-6K Interface Evaluation Module (

The USB connection from the PC provides power, control, and streaming audio data to the EVM for
reduced setup and configuration. The EVM also allows external control signals, audio data, and power for
advanced operation, which allows prototyping and connection to the rest of the evaluation/development
system.
