Te TDA7498E, He Audio Glasce-D Audio Gladelier, e tu ana mo tana Whiringa-rua Whakahoahoa (BTL) Whiriho me te hototahitanga me te puna mana kotahi.Ko enei waahanga ka waiho hei waahanga tino pai mo nga punaha oro a te oro me nga huinga kaikorero whakahoahoa.Te whakamahi i te kete mana 36-pin tino pai, kei roto i te papa kitea, ka whai hua te whakamahana i te wera.Ko tenei ahuatanga ko te mea nui mo te tautoko me te tuku i te koiora i te waa roa.
Ko te Amplifier te whakauru i te hangarau-a-toi toi i arotahi ki te whakaheke i te kaha o te kaha o te kaha, kaore e whakaitihia noa e nga taumahatanga o te taiao.Ko te whakamahinga o te punaha mana kotahi e rere ana i te hoahoa hanganga, te whakarite ngawari i te huihuinga me te pono.Ka taea e koe te whakakaha i te Amplifier mo tana pauna haangai i waenga i te kaha me te kounga o te pai, e whakaatu ana i tana maakete miihini.
I roto i nga whakaurunga oro hou, ka taea e te waahi te aukati kino.Te TDA7498E, me tana hoahoa kaha ano hoki, e tika ana kia tutuki i enei taapiri mokowhiti.Ka puta tona kaha ki te mahi ngawari me te whakaheke i te tono mo te nui o nga punaha paruru.Ka taea e koe te mohio ki te hiranga o te pupuri i nga oro o te oro puta noa i nga ahuatanga rereke.Ka tutuki tenei Amplifier ki te tono mo te whaitake, te whakarato i nga putanga oro-kounga nui ahakoa o nga ahuatanga.
Te TPA3116d2 e kiia ana ko te tino kaha o te absitalio Digital, i whai waahi nui ki te whakatairanga i te hangarau orooto ma te kaha ki te neke atu i te 2ω i te 2ω i tetahi huinga Mono.Ko tenei Amplifier e hangaia ana mo te nui o te whakakotahitanga, e whakaatu ana i tana mohio ma te tuku 2Mo nga ahuatanga e hiahia ana ki te whakarei ake i te mana whakarei ake, ka taea e ia te tuku tika i te 2 × 50 w i te 4ω me nga tono whero.Ko tenei ngawari e poipoia ana ki te maha o nga matea whakarite, te waatea mai i te hikohiko kaihoko ki nga taputapu oro ngaio.
Ko te tohu whiu o te TPA3116D2 ko tana mahi i roto i nga ahuatanga o te Kaiwhakaako me nga pononga pononga.Ka whakamahia e ia he punaha oscillator / poll auaha ki te whakaheke i te wawaotanga, he arai e pa ana ki te kounga tangi me te whakaiti i te koa o te kaupapa.Kei te tautokohia hoki tenei punaha whai hua ki te tukutahi o nga waahanga maha, he kaupapa whai hua mo nga huinga oro riipene e whai kiko ana i te waa horoi.Ka taea e koe te kitea ko tenei kaha tukutahi e whakanui ana i nga mahi a-riiro ma te whakarite i te tohatoha tika puta noa i nga kaikorero katoa.
Ko te Haumaru me te Tika he miro he whatu ki te papanga o te TPA3116D2.He whakauru i nga waahanga tiaki hara whanui penei i te waa-a-waahi, te waiariki, me te huakita.Ko enei tohu ka uru ki te pumau ki te roa me te pumau tonu, ka mau i te kaha o te Amplifier ki nga taumahatanga pea.Ka taea e koe te aro ki enei tiaki i a raatau e tuku ana i a raatau, me te mohio ki nga waahanga ka tiakina mai i nga tupono hiko noa e puta mai ana i te wa e whakahaerehia ana.
