♠ Tele fa'aoga fa'akomepiuta fa'aoga fa'akomepiuta ta'avale quad fa'aola malosi fa'atasi ma fa'ailoga fa'ata'ita'i fa'apipi'i, 'amata taofi' fetaui.
O le TDA7803A o se fa'apipi'i fa'apipi'i fa'apipi'i e tasi i le fa'atekonolosi fa'apitoa BCD fa'atasi: o se fa'aliliuga D/A atoa, fa'aoga numera mo feso'ota'iga tuusa'o i le I2S (po'o le TDM) ma le malosi o le MOSFET vaega o galuega.
Ole fa'aliliuga tu'ufa'atasia D/A fa'ataga ai le fa'atinoga e o'o atu i se tulaga mata'ina 115 dB S/N fa'atasi ma le sili atu i le 110 dB ole fa'aolaola.
E le gata i lea, o le TDA7803A o loʻo tuʻufaʻatasia se manatu fou maualuga maualuga, faʻapitoa mo faʻailoga musika e le faʻaogaina. O le masini ua mamanuina ina ia fetaui ma le faʻaogaina o maa mo faiga vasega-G.
Faʻafetai i lenei manatu, o le faʻaumatia "malosi malosi" i lalo o tulaga faʻalogo masani e mafai ona faʻaititia i le 50% pe a faʻatusatusa i vaifofo masani a le vasega AB.
O le TDA7803A o loʻo tuʻufaʻatasia foʻi se PLL e mafai ona faʻapipiʻiina e mafai ona loka i laina faʻaoga o le 64 * Fs mo faʻasalalauga uma.
O lo'o fa'apipi'iina le masini i se fa'asologa o su'esu'ega atoa e fa'afeso'ota'i le tulaga o failauga ta'itasi e ala ile pasi I2C. Ole pasi lava I2C e mafai ai ona pulea le tele o faʻatonuga o le masini.
O le TDA7803A e mafai ona taina musika i lalo i le 6 V sapalai voltage - o lea e fetaui ma le mea e taʻua o le 'start stop' faʻamatalaga o le maa talu ai nei na faʻaaogaina e le tele o tagata fai taavale (faʻaitiitia ai le suauʻu ma le aʻafiaga o le siosiomaga).
