There is an incorrect equation (4) of op amp’s output voltage in the chapter: 13.9.3 Non-inverting single-ended circuit for input 0 V to 3.3 V (page 147).

At the moment we have the following equation:

     Vout = Vcom * R1 / (R1 + R2)

but it should be:

     Vout = Vcom * R1 / (R1 + R2) + Vin_pos * R2 / (R1 + R2)
