Yes, A is an operator, but it doesn't commute with H. That would imply
the variable measured by A is constant in time. The time per unit
change in the expected value of the variable is the inverse of [d<A>/dt].

d/dt is the derivative operator.
*Can you give one or two specific examples of A? I thought the HUP is
applicable only for non-computing operators. Am I mistaken? AG*
"Non-communting" That's right. But any time varying variable fails to
commute with the Hamiltonian.
