AD7982BRMZ 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. Additionally, use a low-ESR capacitor for the AVDD and DVDD pins, and keep the decoupling capacitors close to the pins.
  • The AD7982BRMZ has an internal calibration circuit that calibrates the ADC during power-up. However, it's recommended to perform an external calibration using an external voltage reference and a calibration signal to ensure optimal accuracy.
  • The AD7982BRMZ can achieve a maximum sampling rate of 1 MSPS. However, the actual sampling rate may be limited by the conversion time, the settling time of the input signal, and the clock frequency. Additionally, the sampling rate may be affected by the input signal bandwidth and the noise floor.
  • The AD7982BRMZ outputs 16-bit data in a serial format. The output data is in a two's complement format, with the most significant bit (MSB) first. The output data can be read using a serial interface, such as SPI or I2C, and can be processed using a microcontroller or a digital signal processor.
  • The AD7982BRMZ has a typical power consumption of 15 mW at 1 MSPS. To minimize power consumption, use the power-down mode when the ADC is not in use, reduce the clock frequency, and use a low-power voltage regulator for the AVDD and DVDD supplies.
