AD7490SRU-EP-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 and digital signals separate. Also, use a low-ESR capacitor for the VDD pin and a 0.1uF capacitor for the AVDD pin. Refer to the ADI application note AN-931 for more details.
  • The AD7490SRU-EP-RL7 has an internal calibration circuit that calibrates the device during power-up. However, it's recommended to perform an external calibration using an external voltage reference and a calibration signal to ensure accurate conversions. Refer to the datasheet section on calibration for more details.
  • The AD7490SRU-EP-RL7 can achieve a maximum sampling rate of 1 MSPS (million samples per second) in normal mode and 500 kSPS in turbo mode. However, the actual sampling rate may vary depending on the system clock frequency, conversion mode, and other factors.
  • The AD7490SRU-EP-RL7 outputs 16-bit digital data in a 2's complement format. The data can be read using a microcontroller or an FPGA. The user needs to ensure proper synchronization and data alignment to avoid data corruption.
  • The AD7490SRU-EP-RL7 has a typical power consumption of 35 mW at 1 MSPS. To reduce power consumption, use the power-down mode, reduce the sampling rate, or use the shutdown mode when not in use. Additionally, use a low-power voltage regulator and optimize the system design to minimize power consumption.
