(typ.) (i o sink 50 a): approx. v ? (v) (t a = 25 c) during designing, consider variations in characteristi cs and temperature characteristics for use with allowance. in addition, also note t hat the output voltage range (v om + ? v om ? ) becomes narrow when an output current increases. o operation of output this ic consist an output level of a class c push-pull. therefore, when a load resi stance is connected to the midpoint potential of v + , v ? , a crossover distortion occurs at the transit ion state of output cu rrent flow direction (source, sink). o handling of ics when stress is added to ics due to warpage or bending of a board, the characteristic fluctuates due to piezoelectric effect. therefore, pay a ttention to warpage or bending of a board.
