AD7949SCPZ-EP-R2 Frequently Asked Questions (FAQ)
-
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 AD7949SCPZ-EP-R2 has an internal calibration circuit that can be enabled by setting the CAL bit in the control register. The device also has an internal voltage reference that can be calibrated using the VREFIN pin. It is recommended to follow the calibration procedure outlined in the datasheet to ensure accurate conversions.
-
The maximum sampling rate of the AD7949SCPZ-EP-R2 is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, the conversion time, and the settling time of the analog input signal.
-
The AD7949SCPZ-EP-R2 outputs 16-bit data in a twos-complement format. The output data can be handled by using a microcontroller or a digital signal processor to read the data from the SPI interface. The output data can be processed and formatted according to the system's requirements.
-
The power consumption of the AD7949SCPZ-EP-R2 is typically 15 mW at 3.3 V and 250 kSPS. To minimize power consumption, the device can be powered down when not in use, and the power-down mode can be controlled using the PDWN pin. Additionally, the device's power consumption can be reduced by reducing the clock frequency and the sampling rate.
