Note: The listed AC/DC and magnetic characteristics are ensured over the operating range of the
integrated circuit. Typical characteristics specify mean values expected over the production
spread. If not other specified, typical characteristics apply at T_j = 25 °C and V_S = 12 V.

even below 1Hz once per magnetic edge, increased phase error is possible.
12 _{Exceeding this limit might result in decreased duty cycle performance. With higher values the}
internal measured signal will be clipped. This will decrease the phase accuracy.
