Note: The listed characteristics are ensured over the operating range of the integrated circuit.
Typical characteristics specify mean values expected over the production spread. If not
otherwise specified, typical characteristics apply at Tj=25°C and the given supply voltage.

10 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.
11 this corresponds to a B0 = 0mT (magnetic offset).
12 depends largely onBmin magnetic signal steepness and also on frequency.
