Explanation: The output voltage for summing amplifier is given Vo =-Va -Vb +Vc +Vd =3-4+6+5 =4v. 12. The output voltage of a summing amplifier is equal to (assume sum of input voltage as Vn )
A. Vn (non-inverting terminal)+ Vn (inverting terminal)
B. Vn (non-inverting terminal)+ (-Vn (inverting terminal)
C. -Vn (non-inverting terminal)+ (-Vn (inverting terminal)
D. -Vn (non-inverting terminal)+ Vn (inverting terminal)
Answer:A
Explanation: The output voltage for summing amplifier is given Vo =-Va -Vb +Vc +Vd =3-4+6+5 =4v. 12. The output voltage of a summing amplifier is equal to (assume sum of input voltage as Vn )
A. Vn (non-inverting terminal)+ Vn (inverting terminal) B. Vn (non-inverting terminal)+ (-Vn (inverting terminal) C. -Vn (non-inverting terminal)+ (-Vn (inverting terminal) D. -Vn (non-inverting terminal)+ Vn (inverting terminal)
Explanation: The output voltage of summing amplifier is equal to sum of the input voltage applied to the non-inverting terminal plus the negative sum of the input voltage applied to the inverting terminal. Sanfoundry Global Education & Learning Series – Linear Integrated Circuit.
