♠ He kaha te kaha o te whakaurunga mamati miihini hiko hiko tapawha me nga waahanga tātaritanga kua oti te hanga, he hototahi te 'tīmatanga mutu'
Ko te TDA7803A ko te maramara kotahi tapawha piriti amplifier i roto i te hangarau BCD matatau te whakauru: he kaitahuri D/A tonu, whakauru mamati mo te hono tika ki te I2S (TDM ranei) me nga waahanga whakaputa MOSFET kaha.
Ko te kaitahuri D/A whakauru ka taea e te mahi te eke ki te 115 dB S/N ōwehenga me te neke atu i te 110 dB o te awhe hihiri.
I tua atu, ko te TDA7803A e whakauru ana i tetahi ariā kaiaka tino auaha, he mea pai hoki mo nga tohu puoro kore e hono. I hangaia te taputapu kia hototahi ki te whakarereketanga pākahiko mo nga punaha akomanga-G.
He mihi ki tenei ariā, ka taea te whakaheke i te "mana whakaputa" i raro i nga tikanga whakarongo toharite ki te 50% ka whakatauritea ki nga otinga o te karaehe AB.
Ko te TDA7803A he whakauru ano i tetahi PLL ka taea te whakahoahoa ka taea te maukati i nga iarere whakauru o te 64*Fs mo nga whirihoranga whakauru katoa.
Kei te taputapu he huinga tātaritanga katoa e whakaatu ana i te mana o ia kaikorero ma te pahi I2C. Ko taua pahi I2C ka taea te whakahaere i nga whirihoranga maha o te taputapu.
Ka taea e te TDA7803A te purei puoro ki raro ki te 6 V ngaohiko tuku - no reira he hototahi ki te ingoa o te 'tīmatanga tu' kōtaha pākahiko i tangohia tata nei e te maha o nga kaihanga waka (na reira ka whakaiti i te kai wahie me te paanga ki te taiao).
