AD8663

Question

Hello, 
 AD8663 datasheet says operating voltage is 5 to 16V or +2,5/-2.5 to +8V/-8V. 
 I have been working on AD8663 supplying it from 3,3 volts (Vpos 3.3V Vneg 0V) without any problems. 
 Is this normal behaviour? 
 
 Regards

Hi auser , 
 The AD8663 will only be able to operate for single supply withing the range of 5V to 16V and for dual supply, within the range of +/-2.5V to +/-8V. With that, I am suggesting to increase your supply to 5V (if you prefer a single supply) or maybe you could try having a -3.3V in your V- as well If the only available supply is 3.3V. 
 I hope this information helps. 
 Thanks, 
 Mae)
