  In this paper we consider Dirac operators in $\mathbb R^n$, $n\geq2$, with a
potential $V$. Under mild decay and continuity assumptions on $V$ and some
spectral assumptions on the operator, we prove a limiting absorption principle
for the resolvent, which implies a family of Strichartz estimates for the
linear Dirac equation. For large potentials the dynamical estimates are not an
immediate corollary of the free case since the resolvent of the free Dirac
operator does not decay in operator norm on weighted $L^2$ spaces as the
frequency goes to infinity.
