AD7985BCPZ-RL7 Frequently Asked Questions (FAQs)

  • A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog signal traces away from the digital signal traces. Also, use a low-ESR capacitor for the AVDD and DVDD pins, and keep the decoupling capacitors close to the pins.
  • The AD7985BCPZ-RL7 has an internal calibration circuit that performs a self-calibration sequence during power-up. No external calibration is required. However, if the user wants to perform an external calibration, it can be done by applying a known voltage to the input and adjusting the offset and gain registers accordingly.
  • The maximum sampling rate of the AD7985BCPZ-RL7 is 1 MSPS. The limitation is due to the internal clock frequency and the settling time of the analog-to-digital converter. The user should ensure that the input signal is properly filtered and settled before the conversion to achieve accurate results.
  • The AD7985BCPZ-RL7 has a power-on reset circuit that ensures the device is in a known state after power-up. The user should ensure that the power supplies are ramped up slowly and the digital interface is not accessed until the device is fully powered up. During power-down, the user should ensure that the power supplies are ramped down slowly to prevent any unwanted conversions.
  • The AD7985BCPZ-RL7 is a high-performance analog-to-digital converter that can dissipate up to 150mW of power. The user should ensure good thermal conductivity between the device and the PCB, and provide adequate airflow to prevent overheating. The device is specified to operate over a temperature range of -40°C to 125°C, and the user should ensure that the device is operated within this range for reliable operation.
