Power Supply Rejection Ratio (PSRR)
PSRR indicates how the output of the DAC is affected by changes
in the power supply voltage.
Voltage Reference TC
Voltage reference TC is a measure of the change in the reference
output voltage with a change in temperature. The reference TC
is calculated using the box method, which defines the TC as the
maximum change in the reference output over a given temperature
range expressed in ppm/°C, as follows:

TempRange is the specified temperature range, −40°C to +85°C.
Load Regulation
Load regulation is the change in reference output voltage due to
a specified change in load current. It is expressed in ppm/mA.
REFmax
REFmin
REFnom
is the minimum reference output measured over the total
