Cirrus Logic provides a recommended layout and routing guide for the WM8988LGECN/RV in their application note AN235. It's essential to follow this guide to ensure optimal performance and minimize noise and interference.
The WM8988LGECN/RV can be configured for different audio interfaces such as I2S, SPI, and AC'97 through register programming. Refer to the datasheet and programming guide for specific register settings and configuration examples.
The recommended power-up sequence for the WM8988LGECN/RV is to apply power to the analog supply (AVDD) first, followed by the digital supply (DVDD). This ensures proper initialization and prevents damage to the device.
To optimize the WM8988LGECN/RV for low power consumption, use the power-down modes, adjust the clock frequency, and optimize the analog and digital supply voltages. Refer to the datasheet and application notes for specific guidelines.
The WM8988LGECN/RV has a maximum junction temperature of 150°C. Ensure proper thermal design and heat dissipation to prevent overheating. Use thermal pads, heat sinks, or other thermal management techniques as needed.
