The integrated circuit (IC) WM8731CLSEFL, produced by Cirrus Logic, is a low-power stereo codec widely used in portable audio devices. This IC not only boasts powerful audio processing capabilities but also integrates multiple functions, making it excel in various audio applications. Below is a detailed introduction to the key features and specifications of WM8731CLSEFL.
Key Features
WM8731CLSEFL is equipped with an efficient headphone driver capable of driving stereo headphone output. This feature makes it ideal for portable MP3 players, voice recorders, and other audio devices. The stereo audio output is buffered and driven by a programmable volume control, providing excellent sound quality and user convenience.
The IC provides stereo line and mono microphone-level audio inputs, along with mute functionality and programmable line-level volume control. This means users can adjust audio input and output parameters as needed to achieve optimal sound quality. Additionally, it offers a bias voltage output suitable for electret microphones, further expanding audio input possibilities.
WM8731CLSEFL supports digital audio input word lengths of 16-32 bits and sampling rates of 8kHz to 96kHz. This feature enables it to handle high-quality audio signals, meeting the needs of various audio applications. It also employs a 24-bit multibit Σ-Δ ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter), combined with oversampling digital interpolation and decimation filters, ensuring high-quality audio conversion.
The IC boasts excellent power management capabilities, controlled via a 2-wire or 3-wire serial interface. This interface provides access to all functions, including volume control, mute, de-emphasis, and extensive power management facilities. Furthermore, it supports multiple power modes, such as play mode and analog bypass mode, allowing flexible configuration based on different application scenarios.
WM8731CLSEFL comes in a 28-pin SSOP or QFN package, with a compact size suitable for portable devices. Its package body material is plastic/epoxy resin, and the package shape is square. The maximum seated height is 0.9mm, with a peak reflow temperature of 260°C, facilitating soldering and assembly during manufacturing.
