A: When compared to hall effect technology, the SSA smart current sensor will offer: • Immunity to stray magnetic fields • Unlike closed loop hall sensors, the SSA has a unipolar power supply requirement • No hysteresis • Low-noise resolution and offset performance allows accurate low-current measurements • Superior offset, gain and linearity performance over entire temperature range • Low noise • Higher bandwidth (300KHz vs 50KHz) • Lighter weight • Superior stability • No sensitivity to conductor positioning • No periodic calibration Here is a document published by Texas Instruments that discusses some of the technical aspects: http://www.ti.com/lit/sbaa293 Q: Is there a derating for temperature?
