1Device is factory-trimmed at 5 V, for optimal accuracy.

2Devices are programmed for maximum accuracy at 5.0 V VCC levels. The device contains ratiometry circuits that accurately alter the 0 A Output Volt-

age and Sensitivity level of the device in proportion to the applied VCC level. However, as a result of minor nonlinearities in the ratiometry circuit ad-

ditional 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.
