Device is factory-trimmed at 5 V, for optimal accuracy.

Devices are programmed for maximum accuracy at 5.0 V VCC levels. The device contains ratiometry circuits that accurately alter the 0 A Output Voltage and Sensitivity

level of the device in proportion to the applied VCC level. However, as a result of minor nonlinearities in the ratiometry circuit additional output error will result when VCC

varies from the 5 V VCC level. Customers that plan to operate the device from a 3.3 V regulated supply should contact their local Allegro sales representative regarding

expected device accuracy levels under these bias conditions.

Guaranteed by design.
