In this paper, we classify the prime spectrum of the quantized Weyl algebra $A_{n}^{\bar{q},\Lambda}$ arising from the quantum differential calculus of G.\ Maltsiniotis on the quantum multiparameter space. $A_{n}^{\bar{q},\Lambda}$ is an algebra of differential operators on this space. It is shown that the set of non-maximal prime ideals is finite of cardinality ${1\over 2}[(2 + \sqrt{2})^n+(2 - \sqrt{2})^n]$. As a consequence, we prove that $A_{n}^{\bar{q},\Lambda}$ is catenary. We also describe explicitly the automorphism group of this algebra. MSC 1991: 16D30, 16P40, 17B37, 16S36, 16S32
