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 x1000000

Vref (T 1− T 2)

The dynamic output impedance, Rz, is defined as:

RZ

=

∆VZ

∆l Z

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:

R1

R' = RZ (1+ R2)
