1Percentage of IP, with IP = 5 A. Output filtered. Up to a 2.0% shift in ETOT may be observed at end-of-life for this device.

2 The Allegro evaluation board has 1500 mm2 of 2 oz. copper on each side, connected to pins 1 and 2, and to pins 3 and 4, with thermal vias connect-

ing the layers. Performance values include the power consumed by the PWB. Further details on the board are available from the ACS704 Frequently

Asked Questions document on our website. Further information about board design and thermal performance also can be found on pages 16 and 17 of

this datasheet.

3RθJA values shown in this table are typical values, measured on the Allegro evaluation board. The actual thermal performance depends on the board

design, the airflow in the system, and thermal interactions between the sensor and surrounding components through the PCB and the ambient air. To

improve thermal performance, see our applications material on the Allegro Web site.
