Voltage requirement?

[jya]

The NMIS4004 spec sheet calls for a ±12V power supply. Looking at the specs of the components that use that supply, I see nothing that would be out of spec with a ±15V supply. Would it be safe to use one?<p>Jerry <p>----------<br>Engineering is the art of making what you want from things you can get.<br>

The minimum voltage requirement for the 12 bit A/D for the NMIS-4004 +/- 12V and the<br>maximum voltage requirement +/- 15V. If you use +/- 15V. The NMIS/L 4004 still work but the AD574 or AD564 will get little warm.<br>Do not go over the maximum requirement voltage. The A/D chip can be fry.
