The ZXCT1050 is a wide input range current monitor, which operates over a range of input voltages from ground up to VCC-2V. As a result the ZXCT1050 can be used on the high or low side of the load. The ZXCT1050 provides variable gain by using two external resistors. The first of which sets the trans conductance and the second setting the overall gain. The very low offset voltage enables a typical accuracy of 1% for sense voltages of only 30mV, giving better tolerances for small sense resistors necessary at higher currents.
