The average temperature coefficient of the reference input voltage, V
, is defined as:
REF
Where:
T
− T
= full temperature change (0-70°C).

V
can be positive or negative depending on whether the slope is positive or negative.
REF
Example: V
= 8.0 mV, V
= 2495 mV, T
− T
= 70°C, slope is positive.

Note 5: The dynamic output impedance, r
, is defined as:
Z
When the device is programmed with two external resistors, R1 and R2, (see
Figure 2
), the dynamic output impedance of the overall circuit, r
, is defined as:
Z
