I can't understand why?
Voltage follower has highest i/p impedence & lowest o/p impedence.

Although the input impedance of most op amps is quite large, the actual input impedance of the circuit depends on the configuration. The noninverting op amp has the highest input impedance, that of the op amp itself.
