Hey, I have the following circuit with the goal of getting a 2.5 volt output and sufficient current to drive a transducer, I have the following in LTspice, however the inverting input to the op amp doesn't equal the non-inverting input of 2.5V, and with V_out = 9.77V, please advise!
The results of the DC operating point analysis are below,
--- Operating Point ---
V(ref_2v5): 2.5 voltage
V(n004): 2.5 voltage
V(n002): 9.77234 voltage

V(neg_ref5v): -5 voltage
V(n003): -4.11005 voltage
V(n001): 5 voltage
