ZXCT1051
Precision wide input range current monitor
Description
The ZXCT1051 is a wide input range current
monitor, which operates over a range of input
voltages from ground up to V
CC
-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.
