General Description

The IXI848A 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 60V, and output gain of up

to 50, the IXI848A is designed to address a wide

variety of current sense applications.

The IXI848A operates over a temperature range of

-40°C to +85°C. The IXI848A is available in an 8-

Lead SOIC package.
