ADS8881CDGS 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 reference voltage (VREF) should be chosen based on the desired full-scale input range. For example, if you need a full-scale input range of 0-5V, you can use a 5V reference voltage. The datasheet provides a table to help select the correct VREF for your application.
  • Clock jitter can affect the ADC's performance, particularly at high frequencies. It's recommended to use a low-jitter clock source, such as a crystal oscillator, and to keep the clock signal path as short as possible to minimize jitter.
  • The ADS8881CDGS outputs data in a serial format, and it's essential to handle the data correctly to avoid errors. You can use a microcontroller or FPGA to receive and process the data. Make sure to follow the datasheet's guidelines for data formatting and timing.
  • The power-on sequence is critical to ensure proper operation. The recommended sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This sequence helps prevent latch-up and ensures correct operation.
