Hi, i need to do voltage shifter
my input from 2.5v to 5 , i need the output to be from 0 to 2.5v , i need to do it by OP AMP and i only have 5v supply to the OP AMP , i do not have negative voltage, so can i do the circuit without using negative voltage

Post a schematic of the circuit in question.

Is this a school assignment that requires you to use an opamp?

Look up differential amp connection for an op amp.

Thanks Crutschow, how can i get ride of the negative voltage of the output of OPAMP is there zero recovery diode?and can i do this circuit without using negative voltage
the circuit convert input from 2.5v to 5v to 0 to 2.5V
