ADS850Y/250 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Additionally, use a low-ESR capacitor for the AVDD pin and a 0.1uF capacitor for the REF pin.
  • Optimize the ADC's performance by selecting the correct clock frequency, adjusting the gain and offset, and using the correct input range and sampling rate for your application. Additionally, consider using the ADC's built-in calibration features and averaging modes to improve accuracy.
  • The recommended power-up sequence is to power up the AVDD pin first, followed by the DVDD pin, and then the clock signal. This ensures that the ADC's internal voltage regulators are properly initialized.
  • The ADS850Y/250 has a pipeline delay of 3 clock cycles. To handle this latency, consider using a FIFO or buffer to store the converted data, and use a synchronization mechanism to ensure that the data is processed in the correct order.
  • The ADS850Y/250's performance can be affected by temperature changes, which can cause gain and offset errors. To compensate for this, consider using temperature sensors and calibration routines to adjust the ADC's gain and offset accordingly.
