Входная цепь перед АЦП

Приведите проще, это уже не помешает, но расширит кругозор. Мне идеология интересна. Плиз.

 

Пожалуйста:

Ub = Uп*R4/(R3+R4) = 8*750/1000 = 6B. Ua = Ub;

U(R2) = -U(R1)*R2/R1 = -2*2/16 = -0.25B;

Uout = Ua + U(R2) = 6 - 0.25 = 5.75B.

Но фокусов здесь никаких нет, тем более, какой-то новой идеологии... :)
