  it is a voltage follower, thus Vout = Vin
  this is a diagram of one:

  another qns:
  
  which statment is wrong when comparing an instrumentation amplifier with a difference amplifier?
  
  A. Both amplifiers subtract the signals between their two input terminals.
  
  B. The difference amplifier has low impedences for both input terminals while instrumentation amplifier has high impedences.
  
  C. The dfference amplifier rejects the common mode signals while the instrumentation amplifier does not.
  
  D. The difference amplifier may be used in place of an instrumentation amplifier only if the signal has low output impedence.
  
  hmmm......
