Note 4. Deviation of reference input voltage, VDEV, is defined as the maximum deviation of the reference over the full

temperature range.

The average temperature coefficient of the reference input voltage αVref is defined as:

Where:

Note 5. The dynamic output impedance, Rz, is defined as:

| Zka | = ∆Vka / ∆Ika

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 :

| Zka | = ∆v / ∆i | ≈ Zka | * ( 1 + R1 / R2)
