DAC Outputs
The MAX16046/MAX16048 feature an 8-bit DAC with 12
outputs (MAX16046) or 8 outputs (MAX16048) for volt-
age margining. Program the voltage on the DAC out-
puts (DACOUT1 –DACOUT12) to trim external
power-supply voltages, by connecting through a series
resistor to the feedback node or to the trim input. DAC
outputs are high impedance during power-up to pre-
vent improper operation of the external power supplies
and must be explicitly enabled by setting the appropri-
ate DACOUT_ enable bits.
Each DACOUT output has three voltage ranges: 0.4V to
0.8V, 0.6V to 1.2V, and 0.8V to 1.6V. Configure DAC
outputs using registers r12h to r14h (see Table 16).
Calculate DACOUT_ voltages, V DACOUT_ , using the fol-
lowing equation:
V DACOUT_ = DAC ACC (V) + ((DAC n - 80h) x
(DAC RNG )/255) (V)
where DAC ACC is the DAC center code absolute accu-
racy and DAC RNG is the DAC output voltage range as
listed in the Electrical Characteristics table and 07h <
DAC n < F8h.
Maxim Integrated
Set any DACOUT_ range configuration register to 00h
to switch off the DACOUT buffer. Set the DACOUT_
enable bit to ‘0’ to leave the DAC output as high imped-
ance. See Table 16 for the registers associated with the
DAC output ranges.
The DAC enable bits are not copied from EEPROM dur-
ing the boot phase; therefore each DACOUT_ output
must be enabled in the r1Ch and r1Dh registers, locat-
ed in the extended page, following power-up. See
Table 17 for the DAC enable bits.
To control the voltage on a particular DAC output, write
the 8-bit binary value to the appropriate output regis-
ter; see Table 18 for the register locations. Although
these registers are located in the default page, they
are not stored in nonvolatile EEPROM and are set to ‘0’
after a POR.
