  We perform a Hamiltonian analysis of the classical type IIB superstring on
AdS(5) x S(5) in the pure spinor approach. Taking the spatial components of the
left-invariant (super)currents and the pure spinor ghosts as canonical
variables, we compute the classical graded Poisson brackets of the currents and
ghosts and identify the first class constraints associated to the local SO(4,1)
x SO(5) symmetry and the pure spinor condition. We then study the properties of
the BRST generators and the Hamiltonian along the constraints. For a natural
choice of the the Lagrange multipliers, we show equivalence of the canonical
equations of motion with the covariant ones. Finally we briefly discuss the
(non) local currents, including the ghost contribution, that generate the
global PSU(2,2|4) symmetry and its Yangian extension in the present framework.
