?癈 Accurate 8-Channel Temperature Sensor
MAX6581
Series-Resistance Cancellation
Some thermal diodes on high-power ICs have exces-
sive series resistance that can cause temperature-mea-
surement errors when used with conventional remote-
temperature sensors. Channels 17 of the MAX6581
have a series-resistance cancellation feature (enabled
by bits [7:0] of the Resistance Cancellation register)
that eliminates the effect of diode series resistance and
interconnection resistance. Set these bits to 1 if the series
resistance is large enough to affect the accuracy of the
channels. The series-resistance cancellation function
increases the conversion time for the remote channels by
125ms (typ). This feature cancels the bulk resistance of
the sensor and any other resistance in series (e.g., wire,
contact resistance, etc.). The cancellation range is from
0I to 100I.
