ADL5910

Hey everyone,

 

I have a quick question, which I can't seem to figure out from the datasheet.

 

I need an envelope detector that will cover a wide frequency range as promised by the ADL5910. It needs to follow a signal like this:

 

 

It seems the ADL5910 does this, although a reset pulse needs to applied after the initial detection, i.e. the device goes high but doesn't decrease in amplitude as the input signal decreases? It seems like it goes high after the threshold voltage is passed and stays high until a reset pulse is applied. I'm hoping I'm completely misunderstanding the datasheet and the device does in fact operate  as shown in the image above?

 

Thanks in advance for any help!
