AD7985BCPZ 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 has an internal calibration circuit that calibrates the ADC during power-up. However, it's recommended to perform an external calibration by applying a known voltage to the input and adjusting the offset and gain registers accordingly.
  • The maximum sampling rate of the AD7985BCPZ is 1 MSPS. However, the power consumption increases with the sampling rate. At 1 MSPS, the typical power consumption is around 15 mW. To reduce power consumption, consider reducing the sampling rate or using the power-down mode.
  • The AD7985BCPZ outputs 16-bit data in a twos-complement format. The output data is available on the D[15:0] pins. The data is output in a serial format, with the most significant bit (MSB) first. The output data can be read using a microcontroller or an FPGA.
  • The recommended input voltage range for the AD7985BCPZ is 0 to VREF (typically 2.5V or 5V). The input voltage range affects the accuracy of the conversions, and it's recommended to keep the input voltage within the specified range to ensure accurate conversions.
