Electrical Characteristics ^(Continued)

DS010055-7

The average temperature coefficient of the reference input voltage,

, is defined as:

REF

Where:

− T = full temperature change (0-70˚C).

can be positive or negative depending on whether the slope is positive or negative.

REF

Example: V

= 8.0 mV, V

= 2495 mV, T − T = 70˚C, slope is positive.

DEV

REF 2 1

Note 6: The dynamic output impedance, r , 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, r , is defined as:
