TAS5711PHPR datasheet by Texas Instruments

TAS5711PHPR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TAS5711PHPR?
  The recommended power-up sequence is to apply PVDD first, followed by AVDD, and then DVDD. This ensures that the internal voltage regulators are powered up in the correct order.
• How do I optimize the TAS5711PHPR for low power consumption?
  To optimize for low power consumption, ensure that the device is operated at the lowest possible clock frequency, disable unused features, and adjust the bias current settings. Additionally, consider using the device's power-down modes when not in use.
• What is the maximum allowed capacitance for the output filters?
  The maximum allowed capacitance for the output filters is 10uF. Exceeding this value may cause stability issues and affect the device's performance.
• Can I use the TAS5711PHPR with a separate analog power supply?
  Yes, the TAS5711PHPR can be used with a separate analog power supply. However, ensure that the analog power supply is well-regulated and has a low noise floor to avoid affecting the device's performance.
• How do I troubleshoot issues with the TAS5711PHPR's I2S interface?
  To troubleshoot issues with the I2S interface, verify that the clock signals are properly aligned, check the data format and bit depth, and ensure that the I2S interface is properly configured. Additionally, use a logic analyzer or oscilloscope to inspect the I2S signals.
