Note 3. Deviation of reference input voltage, V
The average temperature coefficient of the reference input voltage αV
Where:
T2 – T1 = full temperature change.

Note 4. The dynamic output impedance, R
When the device is programmed with two external resistors R1 and R2 (see Figure 2.), the dynamic output
impedance of the overall circuit, is defined as:
