    Can u help me....

    I want to build an encoder sensor using photoreflector that the output is current 4-20mA. How encoders work is only 180 degree clockwise or unclockwise. My plan is using DAC 8bit and AD694 for current output 4-20mA. So guys, can u give me a schematic or anything that i can get started..........

    Thanks b4

    Can you elaborate on your intended hookup? Perhaps a schematic? Going from a photoreflector to an 8 bit DAC is a bit of a stretch.
