ADS8881CDGSR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended layout and routing guide in the ADS8881 Evaluation Module User's Guide (SLAU445). It's essential to follow this guide to ensure optimal performance and minimize noise coupling.
  • The gain setting depends on the input signal range and the desired output voltage range. Refer to the ADS8881 datasheet, section 7.3.1, for a detailed explanation of the gain settings and how to select the correct one for your application.
  • Clock jitter can affect the ADC's performance, particularly in high-frequency applications. Texas Instruments recommends using a low-jitter clock source, such as a crystal oscillator, and following proper PCB layout and routing techniques to minimize clock jitter.
  • To ensure accurate temperature measurement, make sure to follow the guidelines in the ADS8881 datasheet, section 7.3.4. This includes calibrating the temperature sensor, using a low-noise power supply, and minimizing thermal gradients on the PCB.
  • The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures proper initialization and minimizes the risk of latch-up or other power-up related issues.
