OPA4353: Is dual power supply operation possible?

Part Number: OPA4353

This op-amp is described in the datasheet as single power supply operation, but is it possible to operate it with a dual power supply?

    It has features (low supply voltage, rail-to-rail) that allow it to be used in single-supply applications. But it does not care; you can also use dual supplies as long as the total voltage does not exceed 5.5 V.

    Hello, 

    Clemens is correct. The absolute maximum ratings show the supply voltage difference can be up to 5.5 V. This is (V+)-(V-) =5.5V. 

    Looking at the typical performance curves, the device is specified at (V+)-(V-) =5V.  

    Could you share the application's requirements? This part is from 1999, maybe we could offer a device still solves the applications needs with better availability/pricing? 

    All the best,
    Carolina

    Thank you for your clear answers about the op-amp's power supply operation. I now understand it can indeed use dual power supplies, as long as the total voltage is under 5.5V.

    Thank you once again for your helpful assistance.
