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:

Vref

(ppm

⁄ °C)=

Vdev x 1000000

Vref

(T1−T2)

The dynamic output impedance, Rz, is defined as:

∆VZ

∆IZ

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:

R’

=Rz (1+

)
