Wich Supply Voltage for the AD688 is necessary?

Question

Hello community, 
 
 I need a high precision reference voltage for my 16 Bit DAC, so i decided to use the AD688. 
 In the Datasheet the IC is supplyed by a voltage of +-15 V, but in my circuit I have only +-14 V or less. 
 Is it possible to use the AD688 with a +-14 V or +-13 V power supply insted? 
 
 best regards 
 Fabian

Hey Mon, 
 thank you for your response. 
 Of course I noticed the maximum ratings and the specs of the Line regulation... 
 I'm designing a low noise circuit, which is basically a femto ampere current source with a 16 Bit DAC as regulation. So I need a very precision reference to manage the 16 Bit. To prevent power loss I want to use a +-15V and 5V switching regulator with a ultra low noise LDO behind. The LDO are the LT3045 and LT3094. The maximum input voltage of these are 20V and I can adjust the output voltage by a single resistance. To prevent heat and because its a unique pcb +-14V is ok for me. 
 I also think that +-14V will work but I thought that maybe someone had already tested it so I can be sure. It's kind of sad, because it is a very expensive IC so I would expect a clear declaration about the min and max supply voltage.
