AD5933-Slide32

The dynamic range of the input signal on the receive side of the AD5933 can be improved by increasing the value of the I-V gain resistor at the RFB pin. For example, increasing the I-V gain setting resistor at the RFB pin will increase the peak-to-peak signal presented to the ADC input from 400mv (with Rfb=100Ω) to 2Vp-p (with Rfb=500Ω).
