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:

TempRange

REFnom

REFmin

REFmax

where:

VREFmax is the maximum reference output measured over the

total temperature range.

VREFmin is the minimum reference output measured over the total

temperature range.

VREFnom is the nominal reference output voltage, 2.5 V.

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

+105°C.

Thermal Hysteresis

Thermal hysteresis is the voltage difference induced on the

reference voltage by sweeping the temperature from ambient

to cold, to hot, and then back to ambient.
