Ordering Information
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
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°C to +85°C. The IXI848 is available in an 8-
Lead SOIC package.
