Tlhaloso

l Lisebelisoa tsena li na le li-amplifiers tse 'ne tse ikemetseng tse lefelloang ke maqhubu a phahameng tse etselitsoeng ka ho khetheha hore li sebetse ho tsoa phepelong e le' ngoe holim'a mefuta e mengata ea li-voltage. Ts'ebetso e tsoang ho lisebelisoa tse arohaneng e ka khoneha hape ha phapang pakeng tsa lisebelisoa tse peli e le 3V ho 30V (bakeng sa LM2902 le LM2902Q, 3V ho 26V) le Vcc bonyane 1.5V e ntle ho feta motlakase oa mokhoa o tloaelehileng. drain e ikemetse ho boholo ba motlakase oa phepelo.
