3. T he dir ection of t he input curre nt is o ut of the IC d ue to the PN P input stage . Thi s curr ent i s essentially const ant ,
independent of the stat e of the out put, so no loading charge exists on the re ference or input l i nes.
4. T he input common-mode vo ltage of eit her inp ut signal vol t age should not be allow ed to go negative by more than
0.3V .
The upper end of the common- mode voltage r ange is V
