♠ High efficiency digital input automotive quad power amplifier nrog built-in diagnostics nta, 'pib nres' tshaj
Lub TDA7803A yog ib lub nti quad choj amplifier nyob rau hauv advanced BCD technology integrating: ib tug tag nrho D / A converter, cov tswv yim rau kev twb kev txuas ncaj qha rau I2S (los yog TDM) thiab haib MOSFET tso zis theem.
Kev sib koom ua ke D / A converter tso cai rau kev ua haujlwm kom ncav cuag 115 dB S / N piv nrog ntau dua 110 dB ntawm ntau yam dynamic.
Ntxiv mus, TDA7803A integrates ib lub tswv yim tshiab high efficiency, optimized kuj rau uncorrelated music signals.Cov cuab yeej tsim los ua kom haum rau cov roj teeb hloov pauv rau chav kawm-G systems.
Ua tsaug rau lub tswv yim no, lub dissipated "tso zis zog" nyob rau hauv nruab nrab mloog tej yam kev mob yuav txo tau mus txog 50% thaum piv rau cov pa hauv chav kawm ntawv AB kev daws teeb meem.
Lub TDA7803A integrates kuj yog ib tug programmable PLL uas muaj peev xwm xauv ntawm lub input zaus ntawm 64 * Fs rau tag nrho cov input configurations.
Cov cuab yeej tau nruab nrog tag nrho cov kev kuaj mob uas sib txuas lus ntawm txhua tus neeg hais lus los ntawm I2C tsheb npav.Tib lub tsheb npav I2C tso cai rau tswj ntau qhov kev teeb tsa ntawm lub cuab yeej.
Lub TDA7803A muaj peev xwm ua si suab paj nruag mus rau 6 V muab hluav taws xob - yog li nws tau sib xws nrog lub npe hu ua 'pib nres' roj teeb profile tsis ntev los no tau txais los ntawm ntau lub tsheb tsim (yog li txo cov roj noj thiab cuam tshuam rau ib puag ncig).
· AEC-Q100 tsim nyog
· 24-ntsis digital ua
· 115 dB dynamic ntau yam (A-hnyav)
· SB-I (SB – txhim kho) kev ua haujlwm siab ua haujlwm siab tshaj plaws 'tsis yog chav kawm D' ua haujlwm zoo
· Parallel hom muaj nuj nqi muaj
· High tso zis muaj peev xwm:
- 4 x 27 W 4 Ω @ 14.4 V, 1 kHz, THD = 10%
