Summing Amplifier

Figure 4-5 is a single supply summing ampliﬁer. In this

conﬁguration, the output voltage is the sum of V1 and

V2, minus the sum of V3 and V4. By adding more

resistors to either the inverting or non-inverting input,

more voltages may be summed. This single supply

version has one important restriction: the sum of V1

and V2 must exceed the sum of V3 and V4, since the

output voltage cannot pull below zero with only a single

supply.

VOUT

All resistors are equal.

OUT = V1 + V2 – V3 – V4

V1 + V2 > V3 + V4 for single supply operation
