Output voltage : ADA4870

Hi team

I am going to design using ADA4870.
The voltage range is shown in 10 to 40V.
Is plus, minus 20V the maximum?

One question more,
The figure below shows "Up to 60 Vpp 1A with external BJT."
Is the range plus,  minus 30 volts?
Please share the BJT circuit.

Thanks

Damon

    Hello,

    The output voltage range as per data sheet under +/-20V supply are as follows.

    Where as, if you will use single ended supply of +Vs = 40V and -Vs = GND,

    you can expect an output range of 2V to 38V.

    For your 2nd query, we will get back to you if we have the circuit/test condition used to achieve that performance.

    Regards.
