Note 4. Deviation of reference input voltage, VDEV , is defined as the maximum vatiation of the reference over the full temperature
range.
The average temperature coefficient of the reference input voltageαVref is defined as:
…………………….. (PPM/℃)
Where :
T2-T1=full temperature change.
α
Vref can be positive or negativedepending on whether the slope is positive or negative.
Note 4. The dynamic output impedance, Rz, is defined as :
When the device is programmed with two external resistors R1and R2(see Figure 2). The dynamic output impedance of the
overall circuit, is defined as :
