Determine the Vout of Summing Amplifier.
VIN1 = -150mV
VIN2 = + 50mV
VIN3 = +200mV
VIN4 = +100mV
R1 = 1.0kΩ
R2 = 1.0kΩ
R3 = 1.0kΩ
R4 = 1.0kΩ
Rf = 10kΩ
Using the formula for a summing amplifier,
Vout = -Rf * (Vin1/R1 + Vin2/R2 + Vin3/R3 + Vin4/R4)
Substituting the given values,
Vout = -10kΩ * (-150mV/1.0kΩ + 50mV/1.0kΩ + 200mV/1.0kΩ + 100mV/1.0kΩ)
Vout = -10kΩ * (0.2)
Vout = -2.0V
Therefore, the Vout of the summing amplifier is -2.0V.
To determine the Vout of the summing amplifier, we can use the formula for the output voltage of an inverting operational amplifier:
Vout = - (Rf / R1) * (VIN1 + VIN2 + VIN3 + VIN4)
Let's substitute the given values into the formula:
Vout = - (10kΩ / 1.0kΩ) * (-150mV + 50mV + 200mV + 100mV)
Vout = - (10) * (0.1V - 0.05V + 0.2V + 0.1V)
Vout = - (10) * (0.35V)
Vout = -3.5V
Therefore, the Vout of the summing amplifier is -3.5V.
