Multiplying Bandwidth

The multiplying bandwidth is a measure of the finite bandwidth

of the amplifiers within the DAC. A sine wave on the reference

(with full-scale code loaded to the DAC) appears on the output.

The multiplying bandwidth is the frequency at which the output

amplitude falls to 3 dB below the input.

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:

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.

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

+125°C.
