♠ Waxtarka sare ee dhijitaalka ah ee wax-soo-gelinta gawaarida quad-weyneeye oo leh astaamo lagu dhex dhisay, 'start stop' waafaqi
TDA7803A waa hal chip quad buundada cod-weyneeye ee tignoolajiyada horumarsan ee BCD isku dhafka: beddele buuxa oo D/A ah, gelinta dhijitaalka ah ee xidhiidhka tooska ah ee I2S (ama TDM) iyo heerar wax soo saar MOSFET ah oo awood leh.
Beddelka isku dhafan ee D/A wuxuu u oggolaanayaa waxqabadka inuu gaaro saamiga 115 dB S/N ee aad u sarreeya oo leh in ka badan 110 dB ee baaxadda firfircoon.
Intaa waxaa dheer TDA7803A waxay isku daraysaa fikrad hufnaan sare leh oo cusub, oo sidoo kale lagu hagaajiyay calaamadaha muusiga ee aan la isku xidhin. Qalabka waxa loogu talagalay in uu la jaanqaado habaynta batteriga ee nidaamyada-G.
Waad ku mahadsan tahay fikradan, "awoodda wax soo saarka" ee kala daadsan ee xaaladaha dhegeysiga celceliska waa la dhimi karaa ilaa 50% marka la barbar dhigo xalalka heerka caadiga ah ee AB.
TDA7803A sidoo kale waxay isku daraysaa PLL barnaamijaysan oo awood u leh inuu ku xidho soo noqnoqoshada gelinta ee 64*F ee dhammaan qaabaynta wax-gelinta.
Qalabku waxa uu ku qalabaysan yahay qalab baadhitaan oo dhamaystiran kaas oo kala xidhiidhinaya xaalada qof kasta oo hadlaya iyada oo la marayo baska I2C. Isla baska I2C wuxuu u oggolaanayaa inuu xakameeyo dhowr habayn oo qalabka ah.
TDA7803A waxa ay awoodaa in ay muusik ku ciyaarto ilaa 6V danab sahayda ah-marka waxa ay la jaanqaadi kartaa waxa loogu yeero 'start stop' profile batteriga ee ay dhawaan qaateen dhowr baabuur (sidaas darteed yaraynta isticmaalka shidaalka iyo saamaynta deegaanka).
