Let K be a field of characteristic zero complete with respect to a non-trivial, non-Archimedean valuation. We relate the sheaf D of infinite order differential operators on smooth rigid K-analytic spaces to the algebra E of bounded K -linear endomorphisms of the structure sheaf. In the case of complex manifolds, Ishimura proved that the analogous sheaves are isomorphic. In the rigid analytic situation, we prove that the natural map D-> E is an isomorphism if and only if the ground field K is algebraically closed and its residue field is uncountable.
