Wrong opamp specs ?

[l3gi0n]

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: 2*X - 2*Y

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 +/- 5 to +/- 18 ??)


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

Yes, these should be listed in a more clear and consistent manner. For example:

Single supply use: 5V to 36V
Dual supply use: +/- 2.5V to +/- 18V

Is there a website out there that does a better job ?

I would always use the mfr data sheet.
