AD7658BSTZ-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 and digital signals separate. Also, keep the input signals away from the digital signals and use shielding if possible. Refer to the ADI application note AN-931 for more details.
  • The AD7658BSTZ-1 has a self-calibration feature that can be initiated by setting the CAL bit in the control register. This feature calibrates the ADC's offset and gain errors. Additionally, the user can perform an external calibration by applying a known input voltage and adjusting the offset and gain registers accordingly.
  • The maximum sampling rate of the AD7658BSTZ-1 is 250 kSPS. However, this rate can be affected by the clock frequency, conversion mode, and the number of channels being converted. Refer to the datasheet for more details on the sampling rate vs. clock frequency.
  • The AD7658BSTZ-1 has an overvoltage protection circuit that can withstand up to ±16.5 V on the analog input pins. However, it's recommended to use external protection circuitry, such as voltage-limiting resistors and diodes, to prevent damage to the device.
  • The power consumption of the AD7658BSTZ-1 depends on the operating mode, clock frequency, and conversion rate. The typical power consumption is around 35 mW at 250 kSPS. To reduce power consumption, consider using the power-down mode, reducing the clock frequency, or using the low-power mode.
