Using some old school op-amp technology combined with an A/D converter and some DIP switches, I have come up with a digital panel meter. I could not make an IC7106 circuit work for my application no matter what I did so I went the parallax route. Using the 2X16 LCD for the display, the system is quite powerful in terms of ranges and unit display. I can also toggle the negative sign so only the absolute value is displayed. And the decimal point is selectable as well.
The breadboard prototype is functioning and I just got two PCBs made for the final circuit. Once it's fully assembled, I will have some pictures up for viewing.
