What is the Common mode voltage range of ADA4522-2 ?

Hi,

I would like to know the common mode voltage range of ADA4522-2. I am using this as a buffer. The supply voltage to the Op-Amp is ±5 V and my input would be near to 5V( assume 4.9V). What can be my possible output value.?

Thanks in advance.

  • Harry,

    Yes, The output voltage is higher.

    The input impedance of the meter is 1MOhms.

    I tried with a different brand. In-fact the values both of them showing are almost same.. with some mV difference.

    I am probing on the non-inverting input pin and Output pin of AD8639 opamp. 

    As per the datasheet of AD8639, the input resistance is given as 22.5Tohm and closed loop output impedance is given as 4.2Ohms.

    Please help me on this.

    Ashok.
