Cirrus Logic provides a recommended layout and routing guide for the WM8775SEDS/RV in their application note AN231. It's essential to follow this guide to ensure proper operation and minimize noise and interference.
The WM8775SEDS/RV can be configured for different audio formats using the SPI interface. The device has several registers that control the audio format, such as the audio data format, sample rate, and bit depth. Refer to the datasheet and the Cirrus Logic audio codec programming guide for more information.
The power consumption of the WM8775SEDS/RV depends on the operating mode and the clock frequency. According to the datasheet, the typical power consumption is around 120mW in stereo playback mode with a 12.288MHz clock frequency. However, this value can vary depending on the specific application and usage.
The WM8775SEDS/RV has a mute function that can be controlled through the SPI interface. The device has a mute register that can be set to mute the audio output. Additionally, the device also has a soft mute feature that can be used to gradually reduce the audio volume to zero.
The maximum input voltage for the WM8775SEDS/RV is 3.6V. Exceeding this voltage can damage the device. It's essential to ensure that the input voltage is within the recommended range to ensure proper operation and prevent damage.
