TAS5709APHPR datasheet by Texas Instruments

TAS5709APHPR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TAS5709APHPR?
  The recommended power-up sequence is to apply PVDD (analog power) first, followed by DVDD (digital power), and then the clock signal. This ensures proper initialization of the device.
• How do I optimize the TAS5709APHPR's thermal performance?
  To optimize thermal performance, ensure good airflow around the device, use a heat sink if possible, and avoid blocking the thermal pads on the package. Additionally, minimize the power dissipation by optimizing the system design and reducing the current consumption.
• What is the maximum allowed clock jitter for the TAS5709APHPR?
  The maximum allowed clock jitter for the TAS5709APHPR is 100 ppm. Exceeding this value may affect the device's performance and audio quality.
• How do I configure the TAS5709APHPR for mono or stereo audio output?
  To configure the TAS5709APHPR for mono or stereo audio output, use the I2C interface to set the appropriate registers. For mono output, set the MONO bit in the Audio Control Register (ACR) to '1'. For stereo output, set the MONO bit to '0'.
• What is the recommended layout and routing for the TAS5709APHPR's analog and digital signals?
  To minimize noise and interference, keep analog and digital signals separate, use separate power planes for analog and digital supplies, and avoid crossing analog and digital signal traces. Additionally, use a solid ground plane and decouple the power supplies properly.
