... Description The ZXCT1050 is a wide input range current monitor, which operates over a range of input voltages from ground 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 transconductance and the second setting the overall gain ...

... Applications information The ZXCT1050 is a current output version of the ZXCT1051 and as such uses a separate power supply pin. All biasing for the internal amplifiers comes from its separate V powered’, unlike the ZXCT1021. This means that at very small sense voltages the ZXCT1050 draws very little current (<1 A) from the lines being sensed ...
