♠ quad power amplifier e sebetsang hantle haholo ea dijithale e nang le likarolo tsa tlhahlobo e hahelletsoeng ka hare, 'start stop' e tsamaellana.
TDA7803A ke amplifier e le 'ngoe ea chip quad bridge ho kopantseng theknoloji ea BCD e tsoetseng pele: converter e felletseng ea D/A, keno ea dijithale bakeng sa khokahano e tobileng ho I2S (kapa TDM) le mekhahlelo e matla ea tlhahiso ea MOSFET.
Mofetoleli o kopantsoeng oa D/A o lumella ts'ebetso ho fihlela tekanyo e ikhethang ea 115 dB S/N ka ho feta 110 dB ea mefuta e matla.
Ho feta moo, TDA7803A e kopanya mohopolo o mocha o sebetsang hantle, o ntlafalitsoeng le bakeng sa mats'oao a 'mino a sa amaneng. Sesebelisoa se etselitsoe hore se lumellane le ho feto-fetoha ha betri bakeng sa litsamaiso tsa sehlopha sa G.
Ka lebaka la khopolo ena, "matla a sephetho" a lahliloeng tlas'a maemo a tloaelehileng a ho mamela a ka fokotsoa ho fihlela ho 50% ha a bapisoa le litharollo tse tloaelehileng tsa sehlopha sa AB.
TDA7803A e kopanya hape PLL e hlophisehileng e khonang ho notlela maqhubu a ho kenya a 64 * Fs bakeng sa tlhophiso eohle ea ho kenya.
Sesebelisoa se na le tlhahlobo e felletseng ea tlhahlobo e fetisang boemo ba sebui ka seng ka bese ea I2C. Bese e tšoanang ea I2C e lumella ho laola litlhophiso tse 'maloa tsa sesebelisoa.
TDA7803A e khona ho bapala 'mino ho ea ho 6 V phepelo ea motlakase - ka hona e tsamaellana le se bitsoang "start stop" boemo ba betri bo sa tsoa amoheloa ke baetsi ba likoloi ba 'maloa (ka hona ho fokotsa tšebeliso ea mafura le tšusumetso tikolohong).
