♠ I-digital esebenza kahle kakhulu i-automotive quad amplifier yamandla enezici ezakhelwe ngaphakathi zokuxilonga, 'isiqalo sokumisa' esihambisanayo
I-TDA7803A iyi-chip quad bridge amplifier eyodwa kubuchwepheshe obuthuthukisiwe be-BCD obuhlanganisayo: isiguquli esigcwele se-D/A, okokufaka kwedijithali kokuxhumeka okuqondile ku-I2S (noma i-TDM) nezigaba zokuphuma ezinamandla ze-MOSFET.
Isiguquli esihlanganisiwe se-D/A sivumela ukusebenza ukuthi kufinyelele isilinganiso esivelele esingu-115 dB S/N esingaphezu kuka-110 dB wobubanzi obuguqukayo.
Ngaphezu kwalokho i-TDA7803A ihlanganisa umqondo omusha osebenza kahle kakhulu, olungiselelwe namasiginali omculo angahlobene.Idivayisi yakhelwe ukuthi ihambisane nokumodelwa kwebhethri kumasistimu e-class-G.
Ngenxa yalo mqondo, "amandla okukhipha" ahlakaziwe ngaphansi kwezimo zokulalela ezimaphakathi angancishiswa aze afike ku-50% uma kuqhathaniswa nezixazululo ezijwayelekile zekilasi le-AB.
I-TDA7803A ihlanganisa futhi i-PLL ehlelekayo ekwazi ukukhiya kumafrikhwensi okokufaka angu-64*Fs kukho konke ukulungiselelwa kokufaka.
Idivayisi ifakwe uhlu olugcwele lokuxilonga oluxhumana nesimo sesipikha ngasinye ngebhasi le-I2C.Ibhasi elifanayo le-I2C livumela ukulawula ukucushwa okuningana kwedivayisi.
I-TDA7803A iyakwazi ukudlala umculo wehle ufike ku-6 V voltage supply - ngakho ihambisana nalokho okubizwa ngokuthi 'start stop' iphrofayili yebhethri esanda kwamukelwa abenzi bezimoto abambalwa (ngaleyo ndlela yehlisa ukusetshenziswa kukaphethiloli kanye nomthelela endaweni ezungezile).
· I-AEC-Q100 iqeqeshiwe
· 24-bit digital processing
· 115 dB ububanzi obuguqukayo (A-weighted)

- Umdlalo ozimele wangaphambili / wangemuva / uthule
- Izinzuzo ezikhethekayo zedijithali zomsebenzisi wokuphuma komsindo ophansi kakhulu
- Ukuxilongwa kwedijithali ngokutholwa komthwalo we-DC kanye ne-AC
· Ukuhambisana kokumisa (ukusebenza kuze kufike ku-6V)
· Amanani esampula: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz
· Imbobo yedatha ye-serial eguqukayo (1.8 V / 3.3 V):– I2S ejwayelekile, TDM 4Ch, TDM 8Ch, TDM 16ch (8+8ch)
