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

V
can be positive or negative depending on whether the slope is positive or negative.

Example: V
= 8.0 mV, V
= 2495 mV, T − T = 70˚C, slope is positive.

Note 6: 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:
