AD7986BCPZ 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 AD7986BCPZ has an internal calibration circuit that calibrates the ADC during power-up. However, it's recommended to perform an external calibration by writing a known voltage to the input and reading the corresponding digital output to determine the gain and offset errors.
  • The AD7986BCPZ can achieve a maximum sampling rate of 1 MSPS. However, the actual sampling rate may be limited by the system's clock frequency, the conversion time, and the settling time of the input signal.
  • The AD7986BCPZ outputs 16-bit data in a binary two's complement format. The output data can be handled by a microcontroller or an FPGA, and it's recommended to use a FIFO or a buffer to handle the data to avoid data loss.
  • The AD7986BCPZ has a typical power consumption of 15 mW at 1 MSPS. To reduce power consumption, you can reduce the sampling rate, use the power-down mode, or use a lower supply voltage.
