AD8130 5V Single Supply Output Voltage Issue

Hello,

 

I am trying to use the AD8130 in a 5 V single supply circuit as an instrumentation amplifier. The +IN-voltage level is between 1.25 V and 3.75 V at a frequency of 1 MHz and both -IN and REF are tied to 2.5 V. Using unity gain, I would expect the output (R_load = 1k) to follow the voltage at the +IN-pin, but the minimum output voltage according to ADIsimPE is above 2 V.

 

On page 4 of the AD8130 data sheet, the minimum output voltage is mentioned as 1.1 V. Is there something I am missing?

 

Thank you for your help

Seb
