AD7998BRUZ-1 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 signals away from the digital signals. Also, use a low-ESR capacitor for the AVDD and DVDD pins, and keep the analog input traces as short as possible.
  • The AD7998BRUZ-1 has an internal calibration circuit that can be enabled by setting the CAL bit in the control register. The device can also be calibrated externally by applying a known voltage to the input pins and adjusting the offset and gain registers accordingly.
  • The maximum sampling rate of the AD7998BRUZ-1 is 300 kSPS. The power consumption increases with the sampling rate, so it's recommended to use the lowest sampling rate necessary for the application to minimize power consumption.
  • The AD7998BRUZ-1 has internal overvoltage protection on the analog input pins, but it's still recommended to use external protection circuitry such as voltage-limiting resistors or clamping diodes to prevent damage from overvoltage conditions.
  • Yes, the AD7998BRUZ-1 can be used in a multi-channel application by using the channel select pins (CH0-CH3) to select the desired channel. The device can be configured to scan through multiple channels using the auto-increment mode or by using an external microcontroller to control the channel select pins.
