AD7247KNZ Frequently Asked Questions (FAQs)

  • It is recommended to follow a star-grounding configuration, keeping the analog and digital grounds separate, and placing the device close to the analog signal sources. Additionally, ensure that the power supply decoupling capacitors are placed as close as possible to the device's power pins.
  • The internal voltage reference can be configured by connecting the REFOUT pin to the REFIN pin through a resistor (typically 1 kΩ to 10 kΩ) and a capacitor (typically 10 nF to 100 nF) to ground. This creates a voltage divider that sets the reference voltage to the desired level.
  • The maximum sampling rate of the AD7247KNZ is 100 kSPS. As the sampling rate increases, the power consumption also increases. However, the device's power consumption can be reduced by using the power-down mode or by reducing the clock frequency.
  • The AD7247KNZ's digital output data is available in a 16-bit, two's complement format. It is recommended to use a serial interface (such as SPI or I²C) to transfer the data to a microcontroller or other digital system. The data can be formatted as a 16-bit word, with the most significant bit (MSB) representing the sign bit and the remaining 15 bits representing the magnitude.
  • To ensure EMC and EMI compliance, it is essential to follow proper PCB layout and design practices, such as using a solid ground plane, minimizing signal trace lengths, and using shielding and filtering techniques. Additionally, ensure that the device is properly decoupled and that the power supply is well-regulated.
