The average temperature coefficient of the reference input voltage,
∝V
REF, is defined as:
Where:
T2 T1 = full temperature change (0-70C).
∝V
REF can be positive or negative depending on whether the slope is positive or negative.
Example: VDEV = 8.0 mV, VREF = 2495 mV, T2 T1 = 70C, slope is positive.
Note 6: The dynamic output impedance, rZ, is defined as:
When the device is programmed with two external resistors, R1 and R2, (see Figure 2 ), the dynamic output impedance of the overall circuit, rZ, is defined as:
