The set of data points, Vout = 12 V @ Vin = 0 V, Vout = +12 V @ Vin = +3 V, see the transfer curve below.
12 = m(0) + b
12 = m(3) + b
After algebraic manipulation, yield the solution, m = 8 and b = 12, rewrite m and b to new equation.
Vout = 8Vin  12
The equation above similar to the CASE2: Vout = +mVin  b circuit.
We can calculate the value of R1, R2, RF and RG by the following equations:
The circuit configuration which yields a solution is shown below.
Configuration of aMG SIGCONA: Soldering to Jump J5, J7, X2 and X3. Place 5 kΩ resistor to X6, 20 kΩ to X7, 150 kΩ to X8 and 820 Ω to X9 .
The recommended design procedure for zerospan opamp design is:
1.  Substitute the data set into linear equations to obtain m and b (the slope and intercept of a straight line). 
2.  Determine the form of the circuit by m and b then choose the circuit configuration that fits the form. 
3.  Using the circuit equations which selected, calculate the resistor values. 
4.  Build the circuit using aMG SIGCONA. 
5.  Test the circuit, take data and verification.
