Features:
- - Industry-leading noise performance through proprietary amplifier and filter design techniques
- - Integrated shield greatly reduces capacitive coupling from 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
- - Ultra-low power loss: 100 μΩ internal conductor resistance
- - Galvanic isolation allows use in economical, high-side current sensing in high voltage systems

The relationship between voltage output and current input:
VOUT = VOUT(Q) + Vsens x I VOUT(Q) is the quiescent output voltage, which is VCC/2, which is the output voltage when there is no input. Vsens is a sensor-sensitive scale, also known as a coefficient. I is the current flowing from IP+ to IP-.
For example, suppose the sensor model is 050B, VCC is 5V, and I current is 10A, then the output is 5V / 2+40mV/A x10A=2.9V.
