Evaluation and Demonstration Boards and Kits have been designed to help designers with a myriad of applications.

The TLV320AIC15EVM Evaluation Modules (EVMs) features a low power stereo codec with microphone and headphone interface for audio signal processing applications. The TLV320AIC15EVM is becoming increasingly popular due to its low power and small size. It is the ideal platform to evaluate various audio processing algorithms and reference designs.

The board is based on the TLV320AIC15 which is a low power, high performance audio codec device. It supports 16-bit stereo, two channel input/output multiplexing, 48 kHz sample rate, and playback/record from the same or different clocks, as well as support for stereo line-in and out. The TLV320AIC15EVM also supports a variety of digital audio standards, such as I2S, LJ, RJ,TDM, and ADPCM.

The board includes multiple audio connectors and switches for both input and output connections. Other features include microphone pre-amplification, gain control, and opto-isolated digital I/O connections, allowing for multiple board configurations. The board also includes a USB interface for simple communications between the board and a Windows PC for downloading, uploading, and debugging firmware, and providing digital audio frames/streams.

The TLV320AIC15EVM can be used to design and evaluate audio and voice processing applications such as Bluetooth audio streaming, voice over IP, voice recognition, music control, audio conferencing, and musical instruments control. It is also well suited to be used in embedded audio applications like digital cameras, video players, media players and handheld devices.

The main operating principle of TLV320AIC15EVM is to convert analog signals into digital signals which can be processed and manipulated in the processor. The analog input waveform is amplified, filtered, and then converted to a digital bitstream which can be further processed. The digital bitstream is then converted back into an analog signal through the DAC which can be directed to the headphone jack or recorded into a file. The input and output paths of the board are controlled by firmware.

The TLV320AIC15EVM provides all the necessary components and tools to develop audio applications. It includes necessary drivers, GUI (graphical user interface) and software libraries. The board also provides various tools such as oscilloscopes, logic analyzers, pre-programmed digital devices, and debugging software.

In conclusion, TLV320AIC15EVM is a multi-purpose evaluation board designed mainly to help engineers evaluate audio processing algorithms and to develop audio-related edge solutions. The board is highly flexible, and is packed with features and tools to help engineers in their development process.
