Electrical Characteristics (continued) (Ta=25 oC, unless otherwise specified.)
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:
| αVref | = [ VDEV / Vref(25 oC) ] * 106 / T2 – T1…………………….. (PPM/ oC)
Where: T2-T1 = full temperature change.
αVref can be positive or negative depending on whether the slope is positive or negative.
Example: Maximum Vref=2.496V at 30oC, minimum Vref=2.492V at 0oC, Vref=2.495V at 25oC, T=70 oC
| αVref | = [ 4mV / 2495mV ] * 106 / 70oC 23ppm/oC
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)
