Is there any command to help initiate the AD4080 board?

For the pyadi-iio code, the code below will help initialise the board before running https://github.com/analogdevicesinc/pyadi-iio/blob/ad4080/examples/ad4080_example.py . The model the pyadi-iio developers work with is that the ad4080_example.py will configure the ad4080, however, the adf4350 and ad9508, as well as the FGPA need to be all configured together to get the LVDS data synchronized. What may be ultimately needed is an "eval-ad4080-fmcz_example.py" that also configures the components outside of the ad4080 also. One thing we've been trying to work through however is that we needed a non-standard adf4350 driver version, as we use some of the features a little differently on that part. There is a script on the SD-Card however, "ad4080_update_clks.sh" that can be called via a com port or otherwise that runs the necessary commands from Linux, until we've found the best way to call these directly through the python example. Set up the AD4080 configuration ser = serial.Serial( port='COM5', ## CONFIGURE FOR YOUR COM PORT baudrate=115200, parity=serial.PARITY_NONE, stopbits=serial.STOPBITS_ONE, bytesize=serial.EIGHTBITS ) ser.isOpen() ser.flushInput() time.sleep(1) ser.write(b'bash ad4080_update_clks.sh') time.sleep(2) ser.close() Related Links: https://ez.analog.com/other-products/f/q-a/592767/evalad4080fmc-with-pyadi-iio---adf4530-ad9508-configuration-within-python https://github.com/analogdevicesinc/pyadi-iio/blob/ad4080/examples/ad4080_example.py

Q: Do I need to use external power supply decoupling capacitors with the AD4080?

No, supply decoupling capacitors are integrated into the part for optimal performance, saving on BOM and PCB space

Q: What reference voltage can be used with AD4080?

The AD4080 requires a 3V VREF; suitable references are the LTC6655, LTC6655LN, ADR4530, LT6657

Q: What is the the maximum conversion rate and resolution of the AD4080 fast precision SAR converter?

The AD4080 product has a maximum conversion rate of 40 MSPS and a resolution of 20-bits

Q: How many ADC conversion results can be stored in the AD4080’s integrated FIFO memory?

The FIFO can store up to 16384 conversion results. These results can be unprocessed or digital filter processed results.

Q: Does the AD4080 have power saving modes?

Yes, the AD4080 converter can be halted, and analog circuitry put into sleep mode. Data can also be held in an integrated FIFO and read back in the power saving modes.

Q: Can AD4080 be used to detect error conditions on my analog input signal?

Yes, the AD4080 provides a threshold detection function. A user can configure threshold level that will generate an event trigger once crossed.

Q: Can AD4080 accept single ended inputs?

The AD4080's inputs are differential ADC inputs. However, single-ended to differential conversion can be easily achieved in a fully differential amplifier (FDA) driver, such as ADA4945-1.
