___________________Chip Information
Power-Supply Bypassing and Grounding
In most applications, grounding the MAX4172 requires
no special precautions. However, in high-current sys-
tems, large voltage drops can develop across the
ground plane, which can add to or subtract from VOUT.
Use a single-point star ground for the highest current-
measurement accuracy.
The MAX4172 requires no special bypassing and
responds quickly to transient changes in line current. If
the noise at OUT caused by these transients is a prob-
lem, you can place a 1F capacitor at the OUT pin to
ground. You can also place a large capacitor at the RS
terminal (or load side of the MAX4172) to decouple the
load, reducing the current transients. These capacitors
are not required for MAX4172 operation or stability. The
RS+ and RS- inputs can be filtered by placing a capac-
itor (e.g., 1F) between them to average the sensed
current.
