Worst-case conversion time (when $V_{\text {in }}=V_{\text {ref }}$ ):

- Maximum de-integration time: $N_{\text {deint }}=N_{\text {int }}$

- Total max time: $T_{\max }=\left(N_{\text {int }}+N_{\text {deint }}\right) \cdot T_{\text {clock }}=2 N_{\text {int }} T_{\text {clock }}=2 T_{\text {int }}$
