DAC Output Level Transfer Functions
Each of the MAX9979 analog DAC levels is set with a
transfer function that includes the 16-bit DAC code set-
ting, the gain code setting, and the offset code setting.
The V DAC and V VINDAC expressions below present the
basic DAC transfer functions. Each DAC has a voltage
output range of -2.5V to +7.5V (typ). Thirteen of these
DACs are identical and generate a potential according
to the following equation:

Table 23. DAC Transfer Functions
A separate DAC (VIN_) is used for the PMU force value.
This DAC has a finer gain adjustment resolution and fol-
lows the equation:

? ? 64 ? ?
For all DACs, the offset code is an integer value between
0 and 255. The VIN_DAC gain code is an integer value
between 0 and 127, and for all other DACs the gain code
is an integer value between 0 and 63. Offset and gain
codes are based on the calibration register settings.

?
Values for PMU_FI_ gain and PMU_FI_ offset are different
for each PMU current range.
VLDH_ and VLDL_ levels less than zero are truncated.
?
Full-scale range is dependent upon the PMU current range.
Values are 100mA, 4mA, 400μA, 40μA, and 4μA for ranges
A–E, respectively.
? Values for CLAMPHI_ gain, CLAMPLO_ gain, CLAMPHI_ off-
set, and CLAMPLO_ offset vary with PMU force mode and
current range.
