Hi! I'm using the ADA4522-2 as a differential op-amp. According to the tests and simulation results in LTspice, the output differential voltage is approximately 24V. If you use a different operational amplifier, for example, OP2177, this problem disappears and the voltage is 2.5 V. There is an ideal 20 mA differential current source at the input of the circuit.
Can you tell me what the problem may be and how to fix it?
