NOTES
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:
RZ =
∆V
Z
∆I

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’
=R
