WM8281ECS/R Working Principle

The WM8281ECS/R is an integrated stereo audio codec (coder/decoder) with a proprietary design. It contains two high-performance 24-bit ADCs and three high-performance 24-bit DACs, which provide excellent performance for audio A/D and D/A conversions. Additionally, the WM8281ECS/R includes an extensive set of features for advanced audio processing, including a programmable sample rate converter (SRC) and versatile input/output mixing scheme. The integrated headphone amplifier and autonota capability offer superior audio performance for a wide range of audio applications.

The WM8281ECS/R provides an integrated, low-power solution for complete audio processing, from A/D conversion to digital audio processing and output from the DACs. It supports single-ended analog audio input and output as well as digital audio input/output. It provides full support for digital audio I/O, including both I2S and SPDIF interface. Furthermore, the WM8281ECS/R supports a wide range of features, including sample rate conversion, dynamic range control, and an integrated headphone amplifier.

The integrated headphone amplifier integrates a low noise input buffer along with the necessary gain stages, helping to reduce the need for external components. It provides low-distortion and low-noise audio performance, allowing users to listen to their audio recordings with clear sound. The headphone amplifier supports both stereo and mono audio output, and it can be powered separately to provide high-power output to drive headphones.

The WM8281ECS/R integrates programmable SRC to perform sample rate conversions of audio signals on the input. This allows audio signals with different sample rates to be converted without additional external components. The SRC is adjustable to a wide range of supported sample rates from 8kHz to 192kHz.

The autonota feature provides high-quality audio transmission through a digital I2S bus. It offers low-latency transmission of audio signals up to 32 bits/sample, and it is supported by a wide range of features and algorithms to ensure the best possible sound quality. The autonota feature supports multiple audio formats including PCM, AC3, and DTS. Additionally, it supports Dolby digital 5.1 and 7.1 channel configurations.

The WM8281ECS/R is an ideal solution for audio applications where high-quality processing and excellent audio performance are essential. It provides a highly integrated and flexible solution for audio conversion and advanced audio processing. With its low-power operation, small size, and excellent audio performance, the WM8281ECS/R is an ideal solution for portable media players, digital still cameras, DVD recorders, and other consumer electronics applications.
