UPDATE (2.5V)

1. Load ±5V range with the output at 0V. Note that since span and code are updated together, the output, if started at 

0V, will stay there.

2. Load ±10V range with the output at 5V, changing to –5V.

3. Write and update mid-scale code in 0V to 5V range (V

OUT

 = 2.5V) using readback to check the contents of the input 

and DAC registers before updating.
