ZXCT1050
Precision wide input range current monitor
Description
Ordering information
The ZXCT1050 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 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.
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.
