Current DAC circuit L6460
86/139 Doc ID 17713 Rev 1
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
Tabl e 3 5.
By changing LSB current value, all steps will change following this relation:
I
step
(N) = N * I
LSB
where N is the value of DacValue[5:0] bits.
