?癈 Accurate 8-Channel Temperature Sensor
MAX6581
Effect of Ideality Factor
The accuracy of the remote temperature measurements
depends on the ideality factor (n) of the remote diode
(actually a transistor). The default value for the MAX6581
is n = 1.008 (channels 17). A thermal diode on the
substrate of an IC is normally a pnp with the base and
emitter brought out and the collector (diode connection)
grounded. DXP_ must be connected to the anode (emit-
ter) and DXN_ must be connected to the cathode (base)
of this pnp. If a sense transistor with an ideality factor
other than 1.008 is used, the output data is different from
the data obtained with the optimum ideality factor. If
necessary, a different ideality factor value can be chosen
using the Transistor Ideality register (see Table 11). The
Ideality Select register allows each channel to have the
default ideality of 1.008 or the value programmed in the
Transistor Ideality register.
