Hello All,

                  I am using ADL5511 for Envelop detection which will give an voltage corresponding to input RF level.There is a reference

voltage over which the output voltage is changing "EREF" in datasheet.The problem is "EREF" pin in datasheet is changing with temperature and is specified in datasheet,which is not acceptable for our design.Is it acceptable for a chip to behave like this which

is about  to work in specified temperature grade of −40°C to +85°C .Please Advice me.

 

Thanks and Regards,

Anoop G S
