WM8860GEFL/RV Application Field and Working Principle

The WM8860GEFL/RV is one of Wolfson Microelectronics’ family of powerful, integrated audio codecs for multimedia applications including analog-to-digital (A/D) conversion, digital-to-analog (D/A) conversion, and processing of incoming and outgoing sound. As interface codecs, the WM8860GEFL/RV provides a simple, yet complete, solution to audio connectivity requirements within multimedia systems.

The WM8860GEFL/RV supports a wide range of analog and digital input and output formats, allowing it to be used in a wide variety of applications. The codec also offers built-in stereo mixer functionality and supports control of up to 9 discrete volume control inputs. Furthermore, the WM8860GEFL/RV supports several enhanced features that reduce power consumption and optimize audio performance, such as de-emphasis, dynamic boosts and soft mute.

The WM8860GEFL/RV is an ideal solution for a wide range of audio products, including digital media players, mobile devices, set-top boxes, gaming systems, and professional audio equipment. The codec offers an array of features that ensure faultless, high-quality performance.

Working Principle

The WM8860GEFL/RV uses two converters, one for A/D conversion and one for D/A conversion, as well as a programmable digital signal processor that can do audio signal processing and format conversion. This power processor can process and manipulate incoming and outgoing signal in various ways, allowing the user to fine-tune the signal and produce the desired output. This can be done by altering the signal\'s sampling rate, optimizing the pre-emphasis, and enhancing the signal using dynamic boosts and soft mute.

The A/D and D/A converters of the WM8860GEFL/RV are also programmable and can be configured to process a variety of audio inputs and outputs. The codec can process up to 12 mono or 6 stereo input sources, while supporting up to 48 kHz sample rates. This allows a wide range of audio signals to be handled with ease.

The two converters are used in conjunction with the internal digital signal processor. The A/D converter is used for converting analog audio signals into digital signals that can be manipulated and processed, while the D/A converter does the opposite, converting digital signals into analog audio signals to generate the final output. The digital signal processor can be programmed to process incoming and outgoing signals in a variety of ways, enhancing the sound quality, optimizing the signal-to-noise ratio, and reducing distortion.

Conclusion

The WM8860GEFL/RV offers a comprehensive solution for many audio applications. It has powerful, integrated audio codecs that can process a wide range of analog and digital audio formats. The built-in stereo mixer functionality gives users complete control over the audio signal, allowing them to create the desired output. Additionally, the WM8860GEFL/RV offers several features that reduce power consumption and improve audio performance, such as de-emphasis, dynamic boosts and soft mute. Thus, making it an ideal choice for many audio products.
