;TLV320AIC34 evaluation module and USB motherboard


Order now


The TLV320AIC34 evaluation module (EVM) is in the modular EVM form factor, which allows direct evaluation of device performance and operating characteristics, and eases software development and system prototyping. This EVM is compatible with the 5-6K interface evaluation module (5-6KINTERFACE) and additional third-party boards that support the TI modular EVM format.

TLV320AIC34EVM-K is a complete evaluation/demonstration kit that includes a USB-based motherboard called the USB-MODEVM interface board, and evaluation software for use with a personal computer running Microsoft® Windows® operating systems.

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 foradvanced operation, which allows prototyping and connection to the rest of the evaluation/development system.
