The output voltage of this circuit for any code is found to be
V_O = (V_A x (D / 1024) x ((R1 + R2) / R1) - V_A x R2 / R1)
where
• D is the input code in decimal form
• With V_A = 5V and R1 = R2
V_O = (10 x D / 1024) - 5V
A list of rail-to-rail amplifiers suitable for this application are indicated in Table 3.
