Additional Details:

The WM8990ECS/RV is a highly integrated audio codec solution tailored for portable consumer electronics. It combines a high-performance stereo DAC and ADC with Class D speaker drivers and a headphone amplifier. A flexible digital audio interface supports I2S and PCM formats. Control is achieved through a standard I2C interface. The integrated Class D amplifiers are capable of driving speakers directly, eliminating the need for external amplifiers. The CODEC also incorporates a microphone bias circuit, making it suitable for voice recording applications. Digital volume control allows precise adjustment of the audio output level. Low power consumption is achieved through advanced power management techniques, including automatic power-down of unused modules. It's packaged in a small, surface-mount format, making it suitable for space-constrained applications. The high SNR for both DAC and ADC ensures high-fidelity audio playback and recording performance. This part is similar to WM8990ECS, with the /RV often denoting reel packaging or specific revision/testing characteristics.
