Hello, I need to make an op amp circuit that calculates the grade for a subject, where there are 4 types of grade 35% 10% 20% and 35%, within each percentage it is 0-100 points, so I plan to do this :
100%=10mV
Input 0-10mV output 0-3,5mV
Input 0-10mV output 0-1mV
Input 0-10mV output 0-2mV
Input 0-10mV output 0-3,5mV
How can I calculate the values of the resistors so that it gives me the value that I require? and the type of opamp?
