ADT7411
The measured results from the temperature sensors are com-
pared with the internal and external, T
HIGH
, T
LOW
, limits. These
temperature limits are stored in on-chip registers. If the temp-
erature limits are not masked out, any out-of-limit comparisons
generate flags that are stored in Interrupt Status 1 register. One
or more out-of-limit results will cause the INT/INT output to
pull either high or low, depending on the output polarity setting.

Theoretically, the temperature measuring circuit can measure
temperatures from –128°C to +127°C with a resolution of
0.25°C. However, temperatures outside T
A
are outside the guar-
anteed operating temperature range of the device. Temperature
measurement from –128°C to +127°C is possible using an
external sensor.
Temperature measurement is initiated by three methods. The
first method is applicable when the part is in single-channel
measurement mode. The temperature is measured 16 times and
internally averaged to reduce noise. In single-channel mode, the
part is continuously monitoring the selected channel, i.e., as
soon as one measurement is taken, another one is started on the
same channel. The total time to measure a temperature channel
with the ADC operating at slow speed is typically 11.4 ms
(712 μs × 16) for the internal temperature sensor and 24.22 ms
(1.51 ms × 16) for the external temperature sensor. The new
temperature value is stored in two 8-bit registers and ready for
reading by the I
2
C or SPI interface. The user has the option of
disabling the averaging by setting Bit 5 in the Control Config-
uration 2 register (Address 19h). The ADT7411 defaults on
power-up with the averaging enabled.
The second method is applicable when the part is in round
robin measurement mode. The part measures both the internal
and external temperature sensors as it cycles through all
possible measurement channels. The two temperature channels
are measured each time the part runs a round robin sequence.
In round robin mode, the part is continuously measuring all
channels.
Temperature measurement is also initiated after every read or
write to the part when the part is in either single-channel
measurement mode or round robin measurement mode. Once
serial communication has started, any conversion in progress is
stopped and the ADC is reset. Conversion will start again
immediately after the serial communication has finished. The
temperature measurement proceeds normally as described
previously.
