PRELIMINARY TECHNICAL DATA
ADT7316/7317/7318
DAC B HIGH REGISTER
This 8-bit read/write register contains the digital data for
DAC B to convert to an analog representation. As the
ADT7318 has only an 8-bit DAC this register is all that is
is need for it’s DAC B. But in the case of the ADT7316
(12-Bit) and ADT7317 (10-Bit) this register contains the
8 MSBs of the DAC B word.

DAC B LOW REGISTER (ADT7316/17 ONLY)
This 8-bit read/write register conatins the LSBs of the
DAC B word. In the case of the ADT7317 the 2 LSBs are
stored here and for the ADT7316 the 4 LSBs are stored
here.
