General Description
The IXI848 is a precision high side current sense
monitor. High side power-line monitoring offers the
advantage of allowing the ground plane to remain
undisturbed when sensing load currents.
An external sense resistor sets the range of the
amplified   ground-referenced   output   monitoring
voltage. The output voltage is amplified by a
selectable fixed gain of either 10 or 50. With an
input voltage range up to 40V, and output gain of up
to 50, the IXI848 is designed to address a wide
variety of current sense applications.
The IXI848 operates over a temperature range of
-40癈 to +85癈. The IXI848 is available in an 8-
Lead SOIC package.
