Wrong opamp specs?

I have found some wrong specs on mauser.ca …. My understanding is that if:

Supply Type: Dual
Maximum Dual Supply Voltage: Y
Minimum Dual Supply Voltage: X

then: Operating Supply Voltage: 2X - 2Y

Example: OPA604
Supply Type: Dual
Maximum Dual Supply Voltage: +/- 24 V
Minimum Dual Supply Voltage: +/- 4.5 V
Operating Supply Voltage: 9 V to 48 V

Most opamps have the correct specs like this example.

But Here are two examples where the Specs are wrong:

AD8597
Maximum Dual Supply Voltage: 36 V (V- to V+?)
Minimum Dual Supply Voltage: 10 V (V- to V+?)
Operating Supply Voltage: 15 V ???

AD797
Supply Type: Dual
Maximum Dual Supply Voltage: +/- 18 V
Minimum Dual Supply Voltage: +/- 5V
Operating Supply Voltage: 5 V to 18 V (should be 10V to 36V ??)

Is it me or are the specs inconsistent on mouser.ca ?

Is there a website with opamp specs that doesn’t have this problem ?

I would just go to the manufacturer’s site and look at the specs they give.

Just look at the spec sheet from the manufacturer:

Important spec to look for is maximum rail to rail voltage or rail to ground voltage.

Look at the spec sheets, always. Avoids releasing magic smoke due to copy&paste error.
