The analog output voltages are dependent on the total load (typical value 37.5 ), the
digital gain parameters and the I
settings).
The digital output signals in front of the DACs under nominal (nominal here stands for the
settings given in
conditions occupy different conversion ranges, as indicated in
bar signal.
