... Description The ZXCT1051 is a wide input range current monitor, which operates over a range of input voltages from ground 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 ...

... Application information The ZXCT1051 is Zetex’ first current monitor with a separate power supply pin. All biasing for the internal amplifiers comes from its separate V ZXCT1021. This means that at very small sense voltages the ZXCT1051 draws very little current (<1µA) from the lines being sensed. ...

... The internal amplifiers at the heart of the current monitor may well have a bipolar offset voltage but the output cannot go negative. For this reason the ZXCT1051 has been designed to operate in a linear manner over a V range of 10mV to 150mV range, however it will still be monotonic down to V The device has a fixed DC voltage gain of 10 ...
