♠ Babban ingantaccen shigarwar dijital na ƙara ƙarfin wutan lantarki mai ƙarfi tare da ginanniyar fasalin bincike, 'fara tsayawa' masu jituwa
TDA7803A ita ce amplifier guda ɗaya na guntu quad gada a cikin fasahar BCD ta ci gaba da haɗawa: cikakken mai sauya D/A, shigarwar dijital don haɗin kai tsaye zuwa I2S (ko TDM) da matakan fitarwa MOSFET mai ƙarfi.
Haɗaɗɗen D/A mai jujjuyawar yana ba da damar aikin don isa ga fitaccen 115 dB S/N rabo tare da fiye da 110 dB na kewayo mai ƙarfi.
Haka kuma TDA7803A yana haɗa ingantaccen ra'ayi mai inganci, ingantacce kuma don siginonin kiɗan da ba su da alaƙa. An ƙera na'urar don dacewa da daidaitawar baturi don tsarin-G.
Godiya ga wannan ra'ayi, "ikon fitarwa" da aka watsar a ƙarƙashin matsakaicin yanayin sauraron za a iya ragewa har zuwa 50% idan aka kwatanta da na al'ada AB mafita.
TDA7803A yana haɗawa kuma PLL mai shirye-shirye wanda ke iya kullewa a mitocin shigarwa na 64*Fs don duk saitunan shigarwa.
An sanye na'urar tare da cikakkun jeri na bincike wanda ke sadar da matsayin kowane lasifika ta cikin motar I2C. Bas ɗin I2C iri ɗaya yana ba da damar sarrafa saitunan na'urar da yawa.
TDA7803A yana iya kunna kiɗa zuwa 6V samar da wutar lantarki - don haka ya dace da abin da ake kira 'start stop' profile batir kwanan nan wanda masu kera motoci da yawa suka karɓa (don haka rage yawan mai da tasirin muhalli).
