1ICC is equivalent to ICC(max) + 3 mA.

2Time required to initialize device.

3Time required for the output switchpoints to be within speciﬁcation.

4Output Rise Time will be dominated by the RC time constant.

5For lower frequencies, the absolute values of BOP, BRP, and BHYS may decrease due to delay induced by the high-pass ﬁlter.

6 See Deﬁnitions of Terms section.

7 Exceeding the maximum magnetic ﬁeld may result in compromised absolute accuracy.
