5. Deviation of V
When the device is programmed with two external resistors R1 and R2, the dynamic output
impedance of the overall circuit, is defined as:
Where:
T2 – T1 = full temperature change.
αV
positive or negative.
Reference voltage
Deviation of reference voltage over
full temperature range (Note 5)
Ratio of the change in reference
voltage to the change in cathode
