The DAC codes for
±IMARGIN are stored in the DAC-MARGIN-HIGH and DAC-MARGIN-LOW
registers. The codes programmed to these registers, in decimal, is calculated
using:
Using an IOUT range of ±25µA, the equation
becomes:
This is rounded to 189d and 67d to give a IDAC,MAX of 11.9µA and
a IDAC,MIN of –11.9µA.
