♠ 4 x 80W i-digital input class-D isikhulisi somsindo wezimoto esinekhwalithi yomsindo we-Hi-Fi, ukuxilonga okuthuthukile, imvamisa yokushintsha engu-2 MHz kanye Nomkhawulokudonsa Wokulungiswa Okuphezulu
I-HFDA801A iyisikhulisi somsindo esisha se-ST class-D, esidizayinelwe ngokukhethekile izinhlelo zokusebenza zezimoto kubuchwepheshe bakamuva be-BCD. I-HFDA801A ihlanganisa ukuguqulwa kwe-24-bits 120 dB DAC, futhi ifaka isigaba sokuphuma esingu-2 MHz se-PWM sekilasi D. Lokhu kulungiselelwa kuvumela ukuklanywa kohlelo lokusebenza oluhlangene futhi olungabizi, olufinyelela ngesikhathi esifanayo izinga elivelele lokudlalwa komsindo. I-HFDA801A isekela izinhlelo zebhendi ezibanzi (80 kHz), ezinezinga eliphansi kakhulu lomsindo neTHD ephansi. Ngaphezu kwalokho ifaka i-matrix yokuxilonga ephelele kunazo zonke, okuhlanganisa ukuxilonga okugcwele ekudlalweni ukuze kusekelwe izidingo ze-OEM ezidinga kakhulu ngokokulawula kwesipikha nokuqina/ukuthembeka kwesistimu. I-HFDA801A isekela ukuqala kokuyeka ukuncibilika kuze kufike ku-4.5 V (5 V uma ikhanyisa) futhi ifakwe ephaketheni elihlangene nelincane le-LQFP 10x10. Ngakho-ke i-HFDA801A ilungele noma yiliphi izinga lokufaka isicelo sezimoto.
• Ukufaneleka kwe-AEC-Q100 kusaqhubeka

• Ukulungiswa okugcwele kwe-I2C nokuxilonga:
- 4 x Isexwayiso esishisayo kanye nesilinganiso sezinga lokushisa eliphakathi nendawo ku-I 2C (8 bits)
- Ukuxilongwa kwe-AC ne-DC (okuzimele esiteshini)
- Uhlelo lokuvikela lwe-OCP luyalungiseka (4 x umkhawulo we-OCP uyakhetheka)
- Thulisa ukucushwa kwesikhathi
- I-DIM (imitha ye-impedance yedijithali)
- Impendulo ngemva kokulungiswa kwesihlungi
• Amandla okusebenzisa ukuxilonga okuphelele ekudlaleni:
- Kufushane ukuya ku-GND/VCC
- Umtshina we-offset we-DC

- 13 µV A-isisindo; 20 kHz (inzuzo ephezulu) uhlobo
• I-THD ephansi kakhulu:
– 0.02% ku-1 W 1 kHz ekulayisheni okungu-4 no-2 Ω
– 0.08% 20-20 kHz (ibhendi yomsindo ogcwele) emithwalweni engu-4 no-2 Ω (1 W)
• Iphinikhodi ye-CD/Diag (ama-CD akhethiwe ama-threshold angu-3)
• Iphinikhodi yokukhipha yokuvumelanisa (kuphela ngokusakaza okokufaka kwe-TDM, ku-I2Sdata2)

• Isikhathi Sangempela qapha samanje
• Vula Umthwalo ekudlaleni
• Ukulahlwa kwebhethri kuyahambisana (40 V)
• Amasosha omzimba ku-pop/uphawu lomsindo ekuvuleni/kuvalwe, ukushintshashintsha kwebhethri (ngaphakathi kwebanga lokusebenza), ngesikhathi sokuxilonga
• Ukuthobelana kwe-EMI kuhlolwa ngokuya nge-CISPR25
• Ifa (ayikho imodi ye-I2C)
• Izivikelo zesekethe emfishane ezihlanganisiwe
• Ukuvikela okuhlanganisiwe kwe-ESD (2 kV HBM, 500 V / 750 V ekhona CDM)
