Device performance is optimized for the input magnetic range of SENS_COARSE = 4 and input offset of SIG_OFFSET=0. If a different magnetic input range or signal

offset is required, please see the tables in the section EEPROM Customer-Programmable Parameter Reference, near the end of this document.

3

Does not include drift over lifetime and package hysteresis.

4

Offset drifts with temperature changes will be altered from the factory programmed values if Magnetic Input Signal Range is changed. If changes in Magnetic Input Signal

Range cannot be avoided because of application requirements, please contact Allegro for detailed information.
