I don't understand the power supply specification of the op-amp AD826.

The datasheet says:

Specified for +5 V, ±5 V and ±15 V Operation

[...]

The AD826 can operate from a single +5 V supply, while still achieving 25 MHz of bandwidth. Furthermore the AD826 is fully specified from a single +5 V to ±15 V power supplies.

  1. Does it work with a single supply of 8 V or 12 V? 0-8 V

  2. Is the reference to "+5 V to ±15 V" referring to the inverting and non-inverting terminal needing to have a voltage difference of 5 V?

Your quote does not come from the power supply specification in the datasheet. It comes from the abstract, and it refers to the performance specifications being characterized at the mentioned supply voltages.

  1. Did you read the datasheet all the way through? On pp 4 It clearly states the answer to your questions. enter image description here

  2. No. That specification is mentioned elsewhere. See the other two excellent answers for more info on that

  • \$\begingroup\$ thankyou, no I didn't see that datasheet fully but searched online for more than 3hrs my stupidity \$\endgroup\$ – noob_no1 Jan 25 '18 at 13:08

Power supply operating range: -

Absolute maximum voltage between inverting and non-inverting inputs: -

Operationally it might not recommend more than +/- 5 volts

2- is this line "+5 V to ±15 V" says inv and non-inv terminal should have a voltage difference of 5v?

In the data sheet I looked at I couldn't find the line above. For instance, the word "difference" is only used once but not in this context at all.

You need to look at the actual data sheet not the marketing blurb.

enter image description here

From that you can see you can drive it with anything up to 36V between the power pins. You can drive it with 0 and +8V if you wish. What performance you get will be somewhere between the numbers specified at 5V and +-5V (i.e. 10V).

The differential input voltage is the maximum difference between the + and - pins.
