OPERATION—EXAMPLES
1. Load ±5V range with the output at 0V. Note that since span and code are updated together, the output, if started at
2. Load ±10V range with the output at 5V, changing to –5V.
3. Write and update midscale code in 0V to 5V range (V
0V, will stay there. The 16-Bit DAC code is shown in hex for compactness.
