with reference to diagram; comp: means compensation used for avoid output oscilation in special situation. Vref: Reference voltage which determin output current for Full Scale Deflection. 2 outputs: as seen outputs are current souce and need convertion to voltage with use of one opamp.
The noise immune inputs of the DAC0800 series will accept
TTL levels with the logic threshold pin, VLC, grounded.
Changing the VLC potential will allow direct interface to other
