Part Number: ISO7762
Can the ISO7762 be used to translate to a negative voltage? Can it have, say, +3.3V on one side and -3.0V on the other?
Did you mean to say that you would like to convert +3.3V signals to -3.0V signals with respect to a common reference/GND point? If so then yes, this can be achieved using ISO7762 as the device has two independent set of circuits that operate from two supplies independently. The voltage difference between GND1 and GND2 can be anywhere upto 1000V provided the voltages at INx, VCC1 and VCC2 are within the datasheet recommended operating conditions with respect to their local GNDs, GND1 & GND2.
Please find below a simple block diagram that converts +3.3V to -3.0V, please do confirm if this is how you are intending to use ISO7762?
One important point to note is that the device that ISO7762 is connected to should also share the same power supply voltage. Thanks.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Yes, that is how I would like to use it. Here is a slightly more complete diagram of what I would like to do. Can you confirm that this is still doable?
