The average temperature coefficient of the reference input voltage,
V
REF
, is defined as:
Where:
T
2
− T
1
= full temperature change.
V
REF
can be positive or negative depending on whether the slope is positive or negative.
Example: V
DEV
= 6.0mV,
REF
= 1240mV, T

= 125˚C.
Note 5:
The dynamic output impedance, r
Z
, is defined as:
When the device is programmed with two external resistors, R1 and R2, (see
), the dynamic output impedance of the overall circuit, r
