How to choice the resistor power for ADA4700

Hi,

I'm working with the Amplifier ADA4700, I would like to make this below circuit. In the datasheet (see in this attach) I can see : 

High output current drive: 30 mA thus The power at the terminal resistor is about 90 V (if Vin =10V) = 2.7W

 

 

Then If I take a resistor R2=100 Ko standard at 1/4 W, it is not enough for my electronic assembly is this correct my thought ?. I suppose the correct resistor is 100 Ko at 4W for R2. Thanks for your helps
