digiPot Phase inversion

  I was wondering if you had any information on any impact of using a digipot in rheostat mode.  For example, the AD5227, is there any impact to the phase of a signal inputted onto the W and B terminals? 


  Some competitive products do show the phase information and it shows some impact to the signal but I was interested in understanding further if there is any impact to the phase from Analog Devices digipots in general, or specifically the AD5227.
