The frequency response of a real op-amp is well modeled with two parameters: an open-loop DC gain, and a gain-bandwidth product. These two parameters can be modeled in a single Laplace Block.
This example is from the The Ideal Op-Amp (Operational Amplifier) chapter of Ultimate Electronics Book. A real op-amp is well modeled with two parameters: an open-loop DC gain
A_OL and a gain-bandwidth product
GBW, resulting in a one-pole rolloff. This gain is easily modeled by a single Laplace Block element which incorporates both the DC behavior as well as the reduced gain at higher frequencies.
