Temperature Conversion Formula:
1. Positive Temperature = ADC Code/4
2. Negative Temperature = (ADC Code* - 512)/4
*DB9 is removed from the ADC Code
INTERRUPTS
The measured results from the inetrnal temperature sen-
sor, external temperature sensor and the V
DD
pin are com-
pared with the T
HIGH
/V
HIGH
and T
LOW
/V
LOW
limits. These
limits are stored in on-chip registers. Please note that the
limit registers are 8 bits long while the conversion results
are 10 bits long. If the limits are not masked out then any
out of limit comparisons generate flags that are stored in
Interrupt Status 1 Register (address = 00h) and Interrupt
Status 2 Register (address = 01h). One or more out-of
limit results will cause the INTERRUPT output to pull
either high or low depending on the output polarity set-
ting.
Figure 13 shows the interrupt structure for the ADT7316/
17/18. It gives a block diagram representation of how the
various measurement channels affect the INTERRUPT
pin.
THERMAL VOLTAGE OUTPUT
The ADT7316/17/18 has the capability of outputting a
voltage that is proportional to temperature. DAC A output
can be configured to reperesent the temperature of the
internal sensor while DAC B output can be configured to
reperesent the external temperature sensor. Bits 5 and 6 of
Control Configuration 3 register select the temperature
proportional output voltage. Each time a temperature
measurement is taken the DAC output is updated. The
output resolution ADT7318 is 8 bits with 1
°
C change
corresponding to one LSB change. The output resolution
for the ADT7316 and ADT7317 is capable of 10 bits with
0.25
°
C change corresponding to one LSB change. The
default output resolution for the ADT7316 and ADT7317
is 8 bits. To increase this to 10 bits, set bit 1=1 of Con-
trol Configuration 3 register. The default output range is
0V-V
REF
and this can be increased to 0V-2V
REF
. Increasing
the outout voltage span to 2V
REF
can be done by setting
D0 = 1 for DAC A (Internal Temperature Sensor) and
D1 = 1 for DAC B (External Temperature Sensor) in
DAC Configuration register (address 1Bh).
The output voltage is capable of tracking a max tempera-
ture range of -128
°
C to +127
°
C but the default setting is -
40

C to +127
