41/2 Digit AC Powered DPM With Beckman Displays

Analog Devices AD2008 is a 412 digit AC line powered DPM designed for making high accuracy measurements in adverse electrical environments. The AD2008 measures bipolar voltages with a full scale range of :1:1.9999V and an accuracy of :1:0.005% reading :1:50,uV:::1 digit. The fuJl floating, opto-isolated input section provides >100dB of common mode noise rejection at common mode voltages up to 300V RMS even with control signals and optional data outputs connected. In addition, the dual slope integrating conversion technique allows >60dB of normal mode noise rejection at 50 or 60Hz without filtering.
