Description

The ZXCT1051 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 ZXCT1051 can be used on the high or low side of the load.

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.

The ZXCT1051 provides a fixed gain of 10 thereby removing the need for an additional resistor.
