I'm simulating in LTSpice an ADuM3190 to implement an error amplifier, but I need to increase the output voltage of the component.
Doing some testing in simulation, it is implemented at the left side of the component a voltage follower with a triangular wave (0-8 V), as it can be seen in the next figure, and in the right side of the component is introduced a pull-up resistor at 15V with the objetive to increase the output voltage, as is mentioned in the datasheet.
But, after simulating the circuit, it seems that the output is clamped to 2.62V in EAout and 6.85V in EAout2. It could be a problem in the implementation of the circuit or in the other hand, there is some kind of error in the Spice model of the ADuM3190?

Thanks in advanced.
