Total Harmonic Distortion (THD)

THD is the difference between an ideal sine wave and its

attenuated version using the DAC. The sine wave is used as the

reference for the DAC, and the THD is a measurement of the

harmonics present on the DAC output. It is measured in dB.

Voltage Reference Temperature Coefficient (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 tempera-

ture range expressed in ppm/°C, as follows:

REF MAX

REF MIN

REF NOM

TEMP RANGE







where:

VREF_MAX is the maximum reference output measured over the

total temperature range.

VREF_MIN is the minimum reference output measured over the

total temperature range.

VREF_NOM is the nominal reference output voltage, 2.5 V.

TEMP_RANGE is the specified temperature range of −40°C to

+125°C.
