ADT7316ARQ

±0.5°C Accurate Digital Temperature Sensor and Quad Voltage Output 12-/10-/8-Bit DACs

Analog Devices 

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 VOUT-A pin.

On power-up, the voltage output on the VOUT-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 VOUT-A pin. On power-up, the voltage output on the VOUT-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 VOUT-B pin.

On power-up, the voltage output on the VOUT-B pin is 0 V.
