About the power supply voltage of ADG734

Hello


I have a question about the power supply voltage of the ADG734.
In the Features of P1 of the data sheet, it is stated that dual power supplies are ± 2.5V.
Also, regarding the characteristics, there is only ± 2.5V data of P4.
Can this device be used at ± 3.3V?
It seems that the rating has not been exceeded.

Best Regards,
Knj

  • Hi Knj,

    You are correct.  From an AMR (Absolute Max Rating) point of view the part will work with a +/- 3.3V supply (6.6V swing).  The AMR for Vdd to Vss is a 7V swing.  We don't have any test data for this use case and can't guarantee performance, its not recommended. 

    Regards,

    Eric.

  • Hi Knj,

    As Eric has stated the part will operate at a dual supply of +/- 3.3V according to the absolute max ratings, but performance is not guaranteed. So it is not recommended. If you have anymore questions on the ADG734 power supply setup, please post them here.

    Regards,
