The recommended power-up sequence is to apply analog power (AVDD and DVDD) before applying digital power (DVDD). This ensures proper device operation and prevents potential latch-up conditions.
To configure the CS4382-KQZ for master clock mode, set the MCLK pin as the clock source, and ensure that the MCLK frequency is within the specified range (256 fs to 512 fs). Additionally, set the BCLK pin to the desired bit clock frequency.
The maximum allowed capacitance on the analog output pins is 220 pF. Exceeding this value may affect the device's performance and stability.
To optimize the CS4382-KQZ for low power consumption, use the power-down modes (e.g., PDN pin), reduce the clock frequency, and minimize the analog output load. Additionally, consider using the device's built-in power-saving features, such as the automatic power-down mode.
To ensure optimal performance, follow a star-grounding layout, keep analog and digital traces separate, and use a solid ground plane. Additionally, minimize the length of the analog output traces and avoid crossing digital and analog signals.
