PRELIMINARY

LIA130

R00C

Absolute Maximum Ratings are stress ratings. Stresses in

excess of these ratings can cause permanent damage to

the device. Functional operation of the device at conditions

beyond those indicated in the operational sections of this

data sheet is not implied.

1. The deviation parameters V

REF(DEV) and IREF(DEV) are defined as the differences between the maximum and minimum values obtained over the rated temperature range. The average full-

range temperature coefficient of the reference input voltage,

ΔV

REF, is defined as:

ΔV

REF| (ppm/°C) = {VREF (DEV)/VREF (TA 25°C)} X 10

6 /

ΔT

where

ΔT

A is the rated operating free-air temperature range of the device.

2. The dynamic impedance is defined as |Z

OUT| = ΔVCOMP/ΔILED. When the device is operating with two external resistors (see Figure 2), the total dynamic impedance of the circuit is given by:

OUT, TOT| = ΔV/ΔI ≈ |ZOUT| X [1 + R1/R2]
