♠ Ukusebenza okuphezulu kwedijithali igalelo lemoto ye-quad amplifier eneempawu zoxilongo ezakhelwe ngaphakathi, 'ukuqala ukuyeka' kuyahambelana
I-TDA7803A yi-chip eyodwa ye-quad bridge amplifier kubuchwepheshe obuphambili be-BCD edibanisa: i-converter epheleleyo ye-D/A, igalelo ledijithali loqhagamshelwano oluthe ngqo kwi-I2S (okanye i-TDM) kunye nezigaba ezinamandla zokuphuma kwe-MOSFET.
I-converter ye-D / A edibeneyo ivumela ukuba ukusebenza kufikelele kwi-115 dB S / N ratio ebalaseleyo ngaphezu kwe-110 dB yoluhlu oluguquguqukayo.
Ngaphaya koko, i-TDA7803A idibanisa ingqikelelo yobuchule obuphezulu, elungiselelwe imiqondiso yomculo engadibananga. Isixhobo siyilelwe ukuba sihambelane nokumodareyithwa kwebhetri kwiinkqubo zeklasi-G.
Ndiyabulela kule ngcamango, "amandla ophumayo" achithwayo phantsi kweemeko zokuphulaphula eziqhelekileyo zingancitshiswa ukuya kuma-50% xa kuthelekiswa nezisombululo zeklasi ze-AB eziqhelekileyo.
I-TDA7803A idibanisa kwakhona i-PLL ecwangcisiweyo ekwazi ukutshixa kwiifrikhwensi zegalelo ze-64 * Fs kulo lonke ulungelelwaniso lwegalelo.
Isixhobo sixhotyiswe ngoluhlu olupheleleyo lokuxilonga olunxibelelana nobume besithethi ngasinye ngebhasi ye-I2C. Ibhasi ye-I2C efanayo ivumela ukulawula ulungelelwaniso oluninzi lwesixhobo.
I-TDA7803A iyakwazi ukudlala umculo ukuya kuthi ga kwi-6 V amandla ombane - ke iyahambelana nento ebizwa ngokuba 'yisiqalo sokumisa' iprofayili yebhetri esandul' ukwamkelwa ngabenzi beemoto ezininzi (ngaloo ndlela inciphisa ukusetyenziswa kwamafutha kunye nefuthe kokusingqongileyo).
