currently I'am working with the ADM2914 evalboard and wanted to test the function of the ADM2914. I red the schematic and the user guide, but i have no idea how to test the functions of OV and UV. You can set a bunch of voltages which are configurable…
Can you please share the layout files (gerbers) for the EVAL-ADM2914?
attached C program and excel tool are useful for calculating the three-resistor divider for ADM2914 and ADM12914.
You are right about the datasheet error. VH should always connect to the higher voltage potential of the divider.
This error has been logged and will be corrected in the next datasheet revision.
I have the following use case:
- 4 voltages, 1 is negative.
- LATCH is low (remember over voltage)
- TIMER pin with 8.2nF => ~100ms
During startup the TIMER should not trigger /OV vor 100ms (the negative voltage is a lttle late). But after…
The ADM2914 has a nominal current through the resistor divider network. In the provided example in the datasheet, they choose 5uA through both resistor dividers, but didn't explain why that was chosen.
In the example figure 23 they choose different…
yeah - it's the 400MHz one (BF504BCPZ-4F).
VDDINT is 1,4V.
Here are 2 parts of the schematic, maybe you see an obvious mistake I made?
These specs are not quantified under these conditions. i would expect higher input current outside the input voltage range used in test, but not out of the roof.
the max rating section indicates the inputs are not linked/clamped to VCC, so…
