ADS825E Frequently Asked Questions (FAQs)

  • The ADS825E requires careful layout and routing to achieve optimal performance. TI recommends using a 4-layer PCB with a solid ground plane, and keeping the analog and digital signals separate. Additionally, the input and output traces should be kept short and away from noise sources.
  • The ADS825E's analog input impedance can be optimized by selecting the correct input resistor (RIN) and capacitor (CIN) values. TI provides a calculator tool to help determine the optimal values based on the specific application's requirements.
  • The recommended power-up sequence for the ADS825E is to first apply the analog supply voltage (AVDD), followed by the digital supply voltage (DVDD), and then the clock signal. This ensures that the ADC is properly initialized and ready for operation.
  • The ADS825E's digital output data is in two's complement format. The user needs to take care when handling the output data, especially when converting it to a signed or unsigned integer format, to avoid errors and ensure correct interpretation of the data.
  • The ADS825E can operate with clock frequencies up to 20 MHz. However, the maximum clock frequency may be limited by the specific application's requirements and the system's noise tolerance.
