OVERVIEW:
-Integrated shield greatly reduces capacitive coupling from the current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high-voltage applications.
-Total output error improvement through gain and offset trim over temperature.
-Small package size, with easy mounting capability.
-Monolithic Hall IC for high reliability.
-Output voltage proportional to AC or DC currents.
-Factory-trimmed for accuracy.
-Extremely stable output offset voltage.
-Nearly zero magnetic hystereses.
