The WM8918GEFL/V is a low power stereo codec designed by Cirrus Logic. This codec is commonly used in portable audio devices and other applications where high-quality audio and low power consumption are critical. It integrates a stereo digital-to-analog converter (DAC) and an analog-to-digital converter (ADC), along with various audio processing features.

Applications

• Mobile phones
• Portable media players (MP3 players, etc.)
• Tablets
• Gaming devices
• Voice recorders

Features

• Stereo DAC and ADC
• Low power consumption
• Integrated headphone amplifier
• Microphone bias
• Digital volume control
• Various audio processing features (e.g., noise reduction, equalization)
• I2C control interface

Benefits

• Provides high-quality audio playback and recording capabilities.
• Extends battery life in portable devices due to its low power consumption.
• Simplifies system design with its integrated headphone amplifier and microphone bias.

Technical Specifications

The WM8918GEFL/V typically operates on a low voltage supply (e.g., 1.8V or 3.3V). The DAC and ADC resolutions are commonly 24-bit. The signal-to-noise ratio (SNR) and total harmonic distortion plus noise (THD+N) performance are key specifications, typically exceeding 90dB and -80dB, respectively. Consult the official Cirrus Logic datasheet for detailed specifications on voltage ranges, sampling rates, and audio performance metrics.
