Jon,

Some suggestions:

1: Use PWM, filter it, current amplify it (i.e. OP-amp) and divide it.
2: Use a R/2R ladder, current amplify it and divide it.

                        Hi

                        I want my pic to be able to output  8 bit (more
doesn't hurt)  0-1 volt.

                        I was looking at a MAX522 dual DAC it said it could
sink and source 5mA to
                        within .5 volts to ground or vdd.

                        I assume that means that the lowest vout is .5
volts?

                        Do I need a rail to rail DAC?
                        I want to keep component count low any ideas?

                        Thanks

                        Jon
