Current DAC circuit
L6460
The current DAC has three possible current ranges that can be selected using the
DacRange[1:0] bits in the CurrDacCtrl register. The DAC range selection table is shown in
Table 35.

By changing LSB current value, all steps will change following this relation:
Istep(N) = N * ILSB
where N is the value of DacValue[5:0] bits.
