Rpm counting, adjusting and sending analog again

Hello
I have to make a signal (0-5V) that is dependant of rpm
I've got a board of education (full) with a BS2 microcontroller.
My first question, for a input, do I have to count with the mA that the input gets or the Voltage?
So I started with a hall sensor, because the electronic shop can't order a MLX90217, I've got a SS466A from honeywell. The·problem is that it is a latching hall·sensor,·a unipolar will be easier to count impulses and measure rpm?·Then I just got to have 1 magnet...
Then i would like to make a table were I can write the voltage that I want with the specific rpm... but that's maybe for later
At last, I need a DA converter, so I thougt of DAC081C081 http://www.national.com/pf/DA/DAC081C081.html because it can be fed with 5V.
Am I on the right track or complete wrong?
