External Temperature Value Register MSBs (Read-Only)
[Address 0x08]
This 8-bit, read-only register stores the external temperature
value from the external temperature sensor in twos complement
format. The 8 MSBs of the 10-bit value are stored in this register.

DAC A Register LSBs (Read/Write) [Address 0x10]
This 8-bit read/write register contains the 4/2 LSBs of the
ADT7316/ADT7317 DAC A word, respectively. The value in
this register is combined with the value in the DAC A Register
MSBs and converted to an analog voltage on the V
OUT
-A pin.
On power-up, the voltage output on the V
OUT
-A pin is 0 V.

DAC A Register MSBs (Read/Write) [Address 0x11]
This 8-bit read/write register contains the 8 MSBs of the DAC A
word. The value in this register is combined with the value in
the DAC A Register LSBs and converted to an analog voltage on
the V
OUT
-A pin. On power-up, the voltage output on the V
OUT
-A
pin is 0 V.

DAC B Register LSBs (Read/Write) [Address 0x12]
This 8-bit read/write register contains the 4/2 LSBs of the
ADT7316/ADT7317 DAC B word, respectively. The value in
this register is combined with the value in the DAC B register
MSBs and converted to an analog voltage on the V
OUT
-B pin.
On power-up, the voltage output on the V
OUT
-B pin is 0 V.
