Note 5:
DAC switched from all 1s to all 0s, and all 0s to all 1s code.
Note 6:
Sample tested at +25°C to ensure compliance.
Note 7:
Slow rise and fall times are allowed on the digital inputs to facilitate the use of opto-couplers. Only timing for SCL is given
because the other digital inputs should be stable when SCL transitions.
