hi all members,


i'm again here with my same problem, two level power supply is working fine. now i realized that when a lamp fuses the second one will not be exact replacment. now if my input level that was in bright light falls down even below than the desired accuracy the setup fully fails.

now i'm trying to use ADC0804 with a programable referance source, which i plan to design using DAC0808 setup. any suggestions.


thanks


abhishek
