♠ I-4 x 80W igalelo ledijithali iklasi-D iamplifier yomsindo wemoto enomgangatho we-Hi-Fi ye-audio, uxilongo oluphezulu, i-2 MHz yokutshintsha amaza kunye nobubanzi beSisombululo esiPhezulu
I-HFDA801A yi-ST class-D iamplifier yomsindo omtsha, eyenzelwe ngokukodwa usetyenziso lweemoto kubuchwephesha beBCD yamva nje. I-HFDA801A idibanisa i-24-bits 120 dB DAC yokuguqulwa, kunye ne-2 MHz yokutshintshela i-PWM yeklasi ye-D yesigaba sokuphuma. Olu lungelelwaniso lwenza ukuba uyilo lwesicelo esihlangeneyo nesingabizi, ukufikelela ngexesha elifanayo kwinqanaba elibalaseleyo lemisebenzi yomsindo. I-HFDA801A ixhasa usetyenziso lwebhendi ebanzi (80 kHz), enezinga eliphantsi kakhulu lengxolo kunye neTHD ephantsi. Ngaphaya koko ibonakalisa eyona matrix yoxilongo lugqibeleleyo, kubandakanya uxilongo olugcweleyo ekudlaleni ukuxhasa ezona mfuno ze-OEM zifuna kakhulu ngokolawulo lwesithethi kunye nokomelela kwenkqubo / ukuthembeka. I-HFDA801A ixhasa ukuqala ukuyeka ukukrazula ukuya kwi-4.5 V (5 V xa uvula) kwaye igcinwe kwi-compact kakhulu kwaye ibhityile iphakheji ye-LQFP 10x10. Ngaloo ndlela i-HFDA801A ifanelekile kulo naliphi na inqanaba lesicelo semoto.
