[1] Typical values are at TA = 25°C and VCC = 12 V. Performance may vary for individual units, within the specified maximum and minimum limits.

[2] Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.

[3] Negative current is defined as conventional current coming out of (sourced from) the specified device terminal.

[4] Time required to initialize device.

[5] See Definitions of Terms section.

[6] Time required for the output switchpoints to be within specification.

[7] The specification is based on statistical evaluation of a limited sample population.

[8] Load circuit is RL = 100 Ω and CL = 10 pF. Pulse duration measured at threshold of ((ICC(HIGH) + ICC(LOW)) / 2).

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

[10] Exceeding the maximum magnetic field may result in compromised absolute accuracy.
