Design with AD8338

We are designing a receiver with AD8338 as its AGC amplifier. Now we got a problem with the signal input method. We have learned from the data sheet that AD8338's voltage input pins can be driven in either a single-sided or a differential manner. Now we are going to use the first manner, but we are not sure about the features, like gain and noise , whether or not will be affected by our specific design. And if we only use the INPR pin, how to deal with the INPD. We try to connect it to the ground with a capacitor, is it a right choice?


Looking forward to your reply.
