Finding V(out) of Operational Amplifier

Click For Summary
SUMMARY

The discussion focuses on calculating the output voltage (V(out)) of an operational amplifier (Op Amp) powered by ±20V DC. Participants emphasize the importance of identifying known voltages (V1 and V3) and suggest writing equations to sum currents to zero at nodes V0 through V3. The recommended approach involves creating four equations corresponding to the four unknowns (V0, V2, i1, and i2) and utilizing mathematical software for solving these equations.

PREREQUISITES

Hint #1: V1 and V3 are obvious by inspection.

That leaves V0, V2, i1 and i2 as unknowns where i1 and i2 are the op amp output currents.

Write equations summing currents to zero at V0 thru V3. That's 4 equations and 4 unknowns. Stick the equations into your math software.
