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
On power-up, the voltage output on the V
