SBFS042 June 2020 AFE3010
The AFE3010 employs a current-feedback chopper amplifier topology to sense a wide range of fault currents with high precision. The current-feedback topology allows the device to maintain consistent gain across the wide fault current limits. Hence no degradation of accuracy is experienced at large fault current measurements. The device REF, FB, and OUT pins are the noninverting, inverting, and output terminals of the amplifier, respectively. The user access of all three pins helps system designers develop their own current sensing thresholds and bandwidths by optimizing the corresponding passive component values.
