I have a question about the power management of AD5689.
Is it possible to power VDD and VLOGIC independent of each other?
That means I would like to shut down VLOGIC if the device is not in use.
I know that there are Power Down Modes but i…
I made a board with a little routing mistake. I routed /RESET to GND. I don't know if my workaround was successful because i get no voltage at the DACs output.
Do I get back no data from the MISO by default?
Can it be that the module…
DACI have a spicontroller that I am selecting in 12bit mode but writing to a 24 bit device AD5689RBRUZ do I have to use Slave Select or will a independant device select be sufficient. I am getting a output but can not get accurate control. I am asserting…
It is possible to uses an internal voltage reference as exhobited in AD5689R also for another ICs within one project.
How much current it can delivery. I just want two uses two DACs, one with build in Ref Voltage (AD5689R) and one without internal Vref…
Im using an AD5689 16 bit DAC to create DC bias current source, as indicated in the following picture and I'm detecting a high level of low frequency noise.
I represented L1 as an inductor for simplicity but it is a filter with an high…
Is the AD5689 gain select pin classed as a logic pin?
The datasheet says to tie it to VLOGIC or GND, but can I drive it externally as long as I obey the thresholds as shown in Table 2?
The relevant part from Table 2:
Thanks for the help.
AD5689_WriteUpdate_DACREG(DAC_A,1000); // output
HAL_Delay(10); // delay 10ms
AD5689_WriteUpdate_DACREG(DAC_A,50000); // output
I understand your position but as for me I prefer that structure would be described as it is in reality. Some differences between two discussed structures may be observed in noise performance, modulation bandwidth code related effects, stability…
The AD5689 output spectral noise should be 100nV/rtHz, not 300nV/rtHz. This is an edit that we are currently working on as part of an update to the data sheet for that product.
In the AD5689R, figure 12, the vertical scale on the plot should…
