Dear All:
We are doing some simulation about operational amplifiers. I have one question 
about the input of operational amplifiers. If the input impedance of inverting 
input and non-inverting input are not same, does the operational amplifiers 
work normally?

For example, the resistor between vin- and inverting input of operational 
amplifiers is 5K ohm and the resistor between vin+ and non-inverting input of 
operational amplifiers is 50K ohm. Will the operational amplifier work normally?

Best Regards
