Hello,
I am in need of some info on a digital to analogue converter. I am using a picaxe microcontroller to controll a stepper motor via a stepper motor pulse generater and microstep driver as bought from ocean controls. The pulse generator has in one of its options a 5k pot input so you can set two out put frequencies and vary between them using the pot. I want to eliminate the pot and have the micro do it. I need info on a readliy available DIP IC which has either parallel or serial input or both, 8 bit resolution, single polarity 5volt for instance, voltage output and a ref pin which I can connect the 5v ref from the pulse generator.
I have found data on a max522 which looks like it would do the job but farnell only have it in surface mount which is beyond my soldering skills.
Any help would be much appreciated.
