i am using op amp as diiferential atteuator.

the input to the circuit is more than 5 V and and supply for opamp is +_5V. but because of resistor combinations the input coltage at op amp is below 5v. So can we use this ? is there any non linear distortion?

 

Many op amps had show that the input voltage range in the datasheet, maybe they show as Vcc -1.5v, if you using with +/- power, so they will as Vcc-1.5V and -Vcc+1.5V, if you over the range then you have to try that does the output voltage and input voltage following the gain.

As Scott noted, the input voltage range depends upon the on amp. For an input rail-rail type, the input can go between the rails. For standard types the input range is typically within about 1.5V of the rails. That info is give on the op amp data sheet as the common-mode range.

As long as the input is within the op amps rated value, there should be no significant distortion.
