ADS8691IPW Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The datasheet provides a recommended layout and routing guide, but it's also recommended to consult the TI application note 'ADS8691 Layout and Routing Guidelines' for more detailed information.
  • To optimize the performance of the ADS8691IPW in noisy environments, it's recommended to use a low-pass filter on the analog input, use a high-quality power supply, and to decouple the power supply lines. Additionally, using a shielded enclosure and keeping the analog and digital signals separate can help reduce noise.
  • The maximum sampling rate of the ADS8691IPW is 1 MSPS (million samples per second). However, the actual sampling rate may be limited by the system's clock frequency and the conversion time of the ADC.
  • Yes, the ADS8691IPW can operate with a 3.3V power supply. However, the device's performance may be affected, and the maximum sampling rate may be reduced. It's recommended to consult the datasheet and application notes for more information on operating the device at 3.3V.
  • The ADS8691IPW has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and adjusting the internal calibration registers to achieve the desired accuracy. The datasheet provides more information on the calibration process.
