In this article, we present a class of relativistic solutions describingspherically symmetric and static anisotropic stars in hydrostatic equilibrium.For this purpose, we consider a particularized matric potential, namely,Buchdahl ansatz [Phys. Rev. D \textbf{116}, 1027 (1959).] which encompassesalmost all the known analytic solutions to the spherically symmetric, staticEinstein field equations(EFEs) with a perfect fluid source, including inparticular the Vaidya-Tikekar and Finch-Skea. We here developed the model byconsidering an anisotropic spherically symmetric static general relativisticconfiguration that plays a significant effect on the structure and propertiesof stellar objects. We have considered eight different cases for generalizedBuchdahl dimensionless parameter $K$, and analyzed them in a uniform manner. Asa result, it turns out that all the considered cases are valid at every pointin the interior spacetime. In addition to this, we show that the modelsatisfies all the energy conditions and maintains the hydrostatic equilibriumequation. In the framework of the anisotropic hypothesis, we consider analogueobjects with similar mass and radii such as LMC X-4, SMC X-1, EXO 1785-248\emph{etc} to restrict the model parameter arbitrariness. Also, establishing arelation between pressure and density in the form of $P = P (\rho)$, wedemonstrate that EoSs can be approximated to a linear function of density.Despite the simplicity of this model, the obtained results are satisfactory.
