Note 10:
Midscale transition code: 32767 to 32768 for the LTC1592, 8191
to 8192 for the LTC1589, 2047 to 2048 for the LTC1588.

Note 12:
If a continuous clock is used with data changing on the rising
edge of SCK, setup and hold time (t
1
, t
2
) will limit the maximum clock
frequency. If data changes on the falling edge of SCK then the setup time
will limit the maximum clock frequency to 8MHz (continuous 50% duty
cycle clock).
Note 13:
SDO propagation delay and SDI setup time (t
8
, t
1
) limit the
maximum clock frequency for daisy chaining.
