Deviation of reference input voltage, Vdev, is defined as the maximum variation of the
reference input voltage over the full temperature range.
The average temperature coefficient of the reference input voltage, Vref is defined as:
Vmax
Vref
(ppm⁄
°C)=
Vdev x 1000000

Vmin
Vdev = Vmax - Vmin
The dynamic output impedance, Rz, is defined
as:

When the device is programmed with two
external resistors, R1 and R2, (fig 2) , the
dynamic output impedance of the overall
circuit, R, is defined as:
