The real circuit looks as in attachment (capacitances may be a bit different). First op amp has gain of 10, which together with 100 Ohm shunt resistor supplied by transformer 1000:1, gives final ratio 1V/1A. As the op amp input is referenced to half power suppy (2,5V) and his output saturation voltage is ~3,8V, so maximal 1,3V can be produced at output without distortion/saturation. This means that max measurable current is 1,3A peak (~0,92 sinus RMS) - not 5A as declared. Second stage op amp is passed to output by capacitor - may need external level polarization, before entering ADC. Take it into consideration before order.
