PCM3008T/2K datasheet by Texas Instruments

PCM3008T/2K Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the PCM3008T/2K?
  The recommended power-up sequence is to apply VDD first, followed by VCC, and then the analog power supplies (AVDD and DVDD). This ensures proper device operation and prevents latch-up.
• How do I optimize the analog-to-digital converter (ADC) performance for my specific application?
  To optimize ADC performance, ensure proper PCB layout, use a low-noise power supply, and implement a proper analog input filtering scheme. Additionally, adjust the ADC clock frequency and sampling rate according to your application's requirements.
• What is the maximum allowed capacitance for the analog input pins?
  The maximum allowed capacitance for the analog input pins is 10 nF. Exceeding this value may affect the ADC's performance and accuracy.
• Can I use the PCM3008T/2K in a multi-channel audio application?
  Yes, the PCM3008T/2K can be used in multi-channel audio applications. However, you'll need to implement external multiplexing or use multiple devices to accommodate the additional channels.
• How do I handle clock jitter and skew in my design?
  To minimize clock jitter and skew, use a high-quality clock source, ensure proper PCB layout, and implement clock buffering and filtering as needed. Additionally, consider using a clock jitter cleaner or a phase-locked loop (PLL) to further reduce jitter.
