In the original schematic voltage reference is 9.4V so I chose to use two zeners - 3.3V and 6.2V connected in series which should give us 9.5V.Īlso the selected zeners have opposite temperature coefficients which should eliminate each other resulting in excellent temperature stability. This will give us stable reference voltage as the supply voltage is already regulated with LM317. I replaced unnecessary complicated circuit for voltage reference build with IC2 with simple resistor-zener circuit. The resulting schematic was this.Īfter that I decided to simplify the schematic even further. I also made changes in the LED drive circuit and a few other minor changes. Thus total supply voltage for the opamps does not exceed 36V and therefor we may use standard ones.
