Hello,
I have a 4 bit binary input on 4 leads. And I have 4 different ref Vs.
i.e.
refV_1 = 1.0V
refV_2 = 2.2V
refV_3 = 3.75V
refV_4 = 4.9V
binary input would be one of five values hi/low off 4 wires:
0000
1000
0100
0010
0001
How do I get the output of the circuit to be one of the 4 ref Vs (including 0V) for a specific binary input:
0000 = 0V circuit output
1000 = 1.0V circuit output
0100 = 2.2V circuit output
0010 = 3.75V circuit output
0001 = 4.9V circuit output
output will be used as an input ref V for another circuit (comparator). Little current if any.
Please keep in mind that the Ref Vs are user set/adjustable by 4 pots.
Thanks,
Rey
