TLV320AIC3104EVM application field and work principle

Introduction

Evaluation and Demonstration Boards and Kits refers to a group of panels or circuit boards that are used as a test board or integrated circuit board for evaluation and demonstration of the functions and performance of the designed product. One of the most common of which is the TLV320AIC3104EVM from Texas Instruments, a wideband audio playback and system-on-chip (SoC) solution.

Application field

The TLV320AIC3104EVM is designed for audio playback and system-on-chip solutions. As a complete system solution, it can be used for applications such as audio playback, digital audio signal processing, and signal-to-noise ratio improvement. This evaluation board is connected to a variety of audio peripherals, such as amplifiers, speakers, microphones, headphones, line-in devices etc. Through the audio codec, the audio can be sent from the circuitry to an amplifier or speakers.

Working principle

The working principle of the TLV320AIC3104EVM is simple. It has two independent audio CODECs, one for recording and the other for playback. When a signal is recorded, it is analog to digital converter (ADC) and sent through the codec. Digital audio signals (DAC) from the digital audio interface (DAI) are sent to the speaker through the codec. The codec is controlled by a microcontroller (MCU) included in the system. It contains a variety of control parameters and processing registers. It also has an audio processing port, which allows the codec to talk to the MCU. The TLV320AIC3104EVM also includes an audio amplifier, which provides an amplified version of the audio signal from the output of the codec. The codec works with a variety of audio data formats and supports both stereo and mono audio playback.

Conclusion

To sum up, the TLV320AIC3104EVM is a complete system-on-chip (SoC) solution designed for audio playback and recording. It is suitable for a variety of applications such as digital audio signal processing, signal-to-noise ratio improvement, and audio playback. Its working principle is providing two independent audio CODECs, one for recording and the other for playback, connected to audio peripherals and control by a microcontroller.
