Part Number: LM2904
The absolute maximum rating of VCC is stated as ± 13 or 26 V in the data sheet.
My customer want to use Vcc=3.3V,GND=-15V.
If there is a problem please tell me why there is a problem.
Vcc-GND=3.3-(-15)=18 < 26.
Best Regards Koji Hayashi
There shouldn't be a problem with your customer's implementation of the LM2904 at Vcc = 3.3V, GND = -15V since it is within the supply range. One thing to keep in mind, however, is the Common-mode input voltage range and output voltage swing limitations. In this case they both seem to be 1.5V from Vcc.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Koji Hayashi:
Vcc = 0V, GND = -26V would be fine as well since you are still within your maximum supply voltage range (Vcc - GND = 26V). This would be the lowest limit before concerns begin to occur.
