ADS8861IDGSR Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals, and avoid crossing digital signals over analog signals. Also, use a common mode filter or a ferrite bead to filter out high-frequency noise.

  • To optimize the ADC's performance, ensure that the input signal is within the specified range, and use the correct gain setting. Also, adjust the sampling rate and clock frequency according to your application's requirements. Additionally, consider using the ADC's built-in features such as the programmable gain amplifier and the digital filter to improve performance.

  • The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the clock signal. This ensures that the ADC is properly initialized and configured before starting conversions.

  • The ADS8861IDGSR has a latency of 2.5 clock cycles. To handle this latency, ensure that your system can buffer the data and handle the data transfer rate. You can also use the ADC's built-in FIFO to buffer the data and reduce the latency.

  • The ADS8861IDGSR has a built-in calibration feature. To calibrate the ADC, apply a known input voltage and use the ADC's calibration registers to adjust the offset and gain. You can also use an external calibration signal or a calibration module to improve the ADC's accuracy.
