Test board finished

A project log for ProVol-- My 1ppm DAC accuracy Voltage Reference

This project is based on MAX5719A from Maxim. Hopefully, This will the most easily programable voltage reference.

I just finished the test board. The reference of the test boar is REF5040 from TI. I used the 4.096V in my code, but the real voltage is 4.0965V(24℃). I didn’t do any calibration or adjustment in my code. As you can see, the Initial accuracy of the MAX5719A is great.
