... Using two external resistors to set the gain ensures optimal versatility as the transconductance can be varied to meet the output impedance requirements of the load that the ZXCT1020 has to drive. The very low offset voltage enables a typical accuracy of 3% for sense voltages of only 10mV, giving better resistors necessary at higher currents ...

... The ZXCT1020 has a V pin that is used to provide power to the current monitor. The maximum B voltage applied to the ZXCT1020 must be applied to this pin. The S+ and S- pins are used to measure the current flowing to the load through the sense resistor. In normal use, the S+ is tied to V ...
