The average temperature coefficient of the reference input voltage,
∝
V
REF
, is defined as:
Where:
T
2
− T
1
= full temperature change (0-70˚C).
∝
V
REF
can be positive or negative depending on whether the slope is positive or negative.
Example: V
DEV
= 8.0 mV, V
REF
= 2495 mV, T
2
− T
1
= 70˚C, slope is positive.
Note 6:
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
Z
, is defined as:
