Notes:  
4. The deviation parameters V  
and I  
are defined as the differences between the maximum and  
REF(DEV)  
REF(DEV)  
minimum values obtained over the rated temperature range. The average full-range temperature coefficient of the  
reference input voltage, V , is defined as:  
REF  
{VREF(DEV)/VREF(TA = 25°C)} × 106  
VREF (ppm/°C) = ----------------------------------------------------------------------------------------------------  
TA  
where T is the rated operating free-air temperature range of the device.  
A
5. The dynamic impedance is defined as |Z  
| = V  
/ I  
. When the device is operating with two external  
OUT  
COMP  
LED  
resistors (see Figure 2), the total dynamic impedance of the circuit is given by:
