AD71056ARZ

ENGRGY  Metering  Ic  With  Integrated   oscillator and  Reverse polaritv indication

  The ad71056 specifications surpass the accuracy  raquirements  as quoted in the iec62053-21 standard
The only analog circuitry used in the ad 71056  IS  IN THE ADCS and  REFERENCE CIRCUIT ALL OTHER Signal  ProcessinG  such  as  muJtiplication  and  Filtering  is camied  out  in  the  digital  domain  This  approach  provides superior stabilily and  accuracy　over  time  and  in  extreme  environmental  Conditiors 
 
The  AD71056  Supplies  average real  power  information on F1 and  F2 The  low  frequency outputs  These outputs  either directly drive an electromechanical  counter  or  interface with an mcu The high provides instantaneous real power information.
