= 10kHz, 10V peak-to-peak sine wave.

Note 4:

.

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.
