(note 2) stresses beyond those listed under ?bsolute maximum ratings?may cause permanent damage to the device. these are stress rating s only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio ns is not implied. exposure to absolute maximum rating conditions for extended periods may affect device reliability. note 2: if circuit strays in excess of 200pf are anticipated, a 4.7? shunt capacitor will ensure stability under all operating condi- tions. note 3: for military devices, measurements are made at +25?, -55?, and +125?, while for commercial devices measurements are made at +25?, 0?, and +70?. the units are then classified as a function of the worst-case tc. sample tested to 0.1% aql. reverse voltage ..............................................................(note 1) forward current ..................................................................10ma reverse current ..................................................................10ma power dissipation.......limited by max forward/reverse current storage temperature range .............................-65? to +150? operating temperature ranges icl8069c .............................................................0? to +70? icl8069e ..........................................................-40? to +85? icl8069m .......................................................-55? to +125? lead temperature (soldering, 10s) .................................+300? i r = 50?, i r = 500? i r = 500?, t a = operating temperature range (note 3) i r = 500? i f = 500? 10hz f 10khz, i r = 500? conditions ? 12 reverse dynamic impedance ppm/? 10 v 1.20 1.23 1.25 output voltage output voltage temperature coefficient v 0.7 1 forward voltage drop ? 5 rms noise voltage ma 0.050 5 reverse current range units min typ max parameter 0.6 2 50? i r 5ma mv 15 20 output voltage change 50 25 100 icl8069a icl8069d icl8069c icl8069b note 1: in normal use, the reverse voltage cannot exceed the reference voltage. however, when plugging units into a powered-up test fixture, an instantaneous voltage equal to the compliance of the test circuit will be seen. this should not exceed 20v.
