♠ Yakanyanya kushanda zvakanaka dhijitari yekuisa mota quad simba amplifier ine yakavakirwa-mukati diagnostics maficha, 'kutanga kumira' inoenderana
Iyo TDA7803A ndeye imwechete chip quad bhiriji amplifier mune yepamusoro BCD tekinoroji yekubatanidza: yakazara D/A inoshandura, yedhijitari yekubatanidza yakananga kuI2S (kana TDM) uye ine simba MOSFET yekubuda matanho.
Iyo yakabatanidzwa D/A inoshandura inobvumira kuita kuti isvike yakasarudzika 115 dB S/N chiyero ine inodarika 110 dB yeane simba renji.
Zvakare iyo TDA7803A inosanganisa inovamba yepamusoro inoshanda pfungwa, yakagadziridzwa zvakare kune isina kubatana mimhanzi masaini. Chishandiso chakagadzirirwa kuti chienderane nebhatiri modulation yekirasi-G masisitimu.
Kutenda kune iyi pfungwa, iyo yakaraswa "simba rekubuda" pasi peavhareji yekuteerera mamiriro inogona kudzikiswa kusvika 50% kana ichienzaniswa neyakajairwa kirasi AB mhinduro.
Iyo TDA7803A inosanganisa zvakare chirongwa chinogoneka PLL inokwanisa kukiya pamafaro ekuisa e64*Fs kune ese magadzirirwo ekuisa.
Mudziyo uyu wakashongedzerwa neakazara diagnostics array iyo inotaurira mamiriro emutauri wega wega kuburikidza neI2C bhazi. Iyo imwechete I2C bhazi inobvumira kudzora akati wandei magadzirirwo emudziyo.
Iyo TDA7803A inokwanisa kuridza mimhanzi ichidzika kusvika pa6 V magetsi ekupa - saka inofambirana neinonzi 'start stop' bhatiri mbiri yakagamuchirwa nevagadziri vemotokari vakati wandei (zvichidaro kuderedza kushandiswa kwemafuta uye kukanganisa pamusoro penharaunda).
· AEC-Q100 inokwanisa
· 24-bit digital kugadzirisa
· 115 dB simba renji (A-yakayerwa)
· SB-I (SB - yakavandudzwa) kushanda kwepamusoro-soro kwepamusoro-soro 'isina-kirasi D' kunyatsoshanda
· Parallel mode basa kuwanikwa
· Yakakwira kubuda simba kugona:
– 4 x 27 W 4 Ω @ 14.4 V, 1 kHz, THD = 10%
– 4 x 47 W 2 Ω @ 14.4 V, 1 kHz, THD = 10%
· Flexible mode control:
- Yakazara I2C bhazi kutyaira 1.8V / 3.3V) ine mana kero inosarudzwa (chete yePowerSO36 package sarudzo)
- Yakazvimirira kumberi / kumashure kutamba / mbeveve
-Anosarudzwa madhijitari anowanikwa kune yakaderera-yakaderera ruzha mutsara-kunze basa
- Digital diagnostic neDC uye AC kuomerwa kwekuona
· Kutanga-kumisa kuenderana (kushanda pasi kusvika ku6V)
Mwero yemuenzaniso: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz
* Flexible serial data port (1.8 V / 3.3 V):- I2S yakajairwa, TDM 4Ch, TDM 8Ch, TDM 16ch (8+8ch)
· Offset detector
· Yakazvimirira kumberi/kumashure clipping detector
· Programmable diagnostic pini
· CMOS inoenderana inogonesa pini
· Dziviriro yekupisa
· Pop yemahara mumbeveve kutamba shanduko uye viceversa
