AD605: FAQ

  • AD604 / AD605 : group delay and channel to channel phase variance

    Question Do you have any information as to the variation in phase between the two channels of the AD605 as the gain is changed? Answer We have no phase information for the AD605, but we do have some…
  • AD605 PGA in ultrasonic flow meter

    Question I see quite large input impedance variation specified in the datasheet. Now I wonder, is the input impedance varying with the gain? Or is it just varying per device and constant over gain…
  • AD605: Noise vs gain

    Question The noise figure f( Vgn) is given for a 20dB/V scaling ( cf page 5 of the DS ). What will it be for a 40dB/V ?? Answer I don't have any measured results to give you, but the basic idea is that…
