ADS8405IBPFBT Frequently Asked Questions (FAQs)

  • 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.
  • The ADS8405IBPFBT has an internal calibration circuit that is enabled by applying a voltage to the CAL pin. The calibration process is initiated by applying a voltage to the CAL pin and then releasing it. The device will then perform a self-calibration sequence. It is recommended to perform calibration after power-up and after any changes to the reference voltage or clock frequency.
  • The recommended clock frequency for the ADS8405IBPFBT is between 1 MHz and 20 MHz. The conversion rate is directly proportional to the clock frequency. A higher clock frequency will result in a faster conversion rate, but may also increase power consumption and noise sensitivity.
  • The ADS8405IBPFBT has internal overvoltage protection up to 5V, but it is still recommended to use external protection circuitry such as voltage-limiting resistors or clamping diodes to prevent damage from excessive voltage. For undervoltage conditions, it is recommended to use a voltage regulator or a voltage supervisor to ensure a stable voltage supply.
  • 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 analog circuitry is powered up before the digital circuitry, which helps to prevent unwanted digital noise from affecting the analog signals.
