CS5511-ASZ Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the CS5511-ASZ?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures proper internal biasing and prevents latch-up.
• How do I optimize the analog input filter for my specific application?
  The optimal filter configuration depends on the specific application and signal characteristics. Consult the Cirrus Logic application note AN215 for guidance on filter design and optimization.
• What is the maximum allowed input voltage for the analog input pins?
  The maximum allowed input voltage for the analog input pins is VCC + 0.3V. Exceeding this voltage may cause damage to the device.
• How do I ensure accurate conversion results in noisy environments?
  Use the internal clock or an external clock with a low jitter (< 100 ps) to minimize conversion errors. Additionally, consider using a noise filter or shielding to reduce electromagnetic interference.
• What is the recommended layout and routing for the CS5511-ASZ?
  Follow the guidelines in the Cirrus Logic application note AN216 for PCB layout and routing recommendations to minimize noise and ensure optimal performance.
