Impinduka nziza cyane ya enterineti yinjiza amamodoka quad power amplifier hamwe nuburyo bwo kwisuzumisha, 'tangira guhagarara' birahuye
TDA7803A nigikoresho kimwe cya chip quad ikiraro cyongera imbaraga muburyo bwa tekinoroji ya BCD ihuza: D / A yuzuye, kwinjiza imibare kugirango uhuze neza na I2S (cyangwa TDM) hamwe nibisohoka bikomeye bya MOSFET.
Ihinduranya D / A ihindura imikorere ituma imikorere igera ku kigereranyo cya 115 dB S / N hamwe na 110 dB zirenga.
Byongeye kandi, TDA7803A ihuza uburyo bushya bwo gukora neza, butezimbere kandi kubimenyetso byumuziki bidafitanye isano.Igikoresho cyashizweho kugirango gihuze na bateri ya moderi ya sisitemu-G.
Bitewe niki gitekerezo, "gusohora imbaraga" zitandukanijwe mugihe cyo gutega amatwi zishobora kugabanuka kugera kuri 50% mugihe ugereranije nicyiciro gisanzwe AB ibisubizo.
TDA7803A ihuza kandi PLL ishobora gutegurwa ishoboye gufunga inshuro zinjira za 64 * Fs kubintu byose byinjijwe.
Igikoresho gifite ibikoresho byuzuye byo gusuzuma byerekana imiterere ya buri muvugizi binyuze muri bisi ya I2C.Bisi imwe ya I2C yemerera kugenzura ibice byinshi byigikoresho.
TDA7803A ishoboye gucuranga kugeza kuri 6 V itanga amashanyarazi - bityo rero irahuza nicyo bita 'start stop' umwirondoro wa batiri uherutse kwemezwa nabakora imodoka nyinshi (bityo bikagabanya ikoreshwa rya lisansi ningaruka kubidukikije).
· AEC-Q100 yujuje ibyangombwa
· Gutunganya 24-bit bitunganijwe
· 115 dB ingero zingana (A-uburemere)
· SB-I (SB - yatejwe imbere) imikorere ikora neza cyane 'itari icyiciro D' ikora neza
· Imikorere ibangikanye imikorere irahari
· Ubushobozi bwo gusohora ingufu nyinshi:
- 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%
Kugenzura uburyo bworoshye:
- Bisi yuzuye ya I2C itwara 1.8V / 3.3V) hamwe na adresse enye zishobora gutoranywa (gusa kuri pack ya PowerSO36)
- Kwigenga imbere / gukina inyuma / kutavuga
- Guhitamo ibyatoranijwe byunguka kubikorwa byurusaku ruto cyane
- Gusuzuma Digital hamwe na DC hamwe na AC
· Gutangira-guhagarika guhuza (imikorere kugeza kuri 6V)
· Ibipimo by'icyitegererezo: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz
· Icyerekezo cyamakuru cyoroshye (1.8 V / 3.3 V): - I2S isanzwe, TDM 4Ch, TDM 8Ch, TDM 16ch (8 + 8ch)
· Offset detector
· Icyuma cyigenga imbere / inyuma cyo gukuramo ibyuma
· Porogaramu ishobora kwisuzumisha pin
· CMOS ihuza ifasha pin
Kurinda ubushuhe
· Pop yubusa mubiragi kugirango ikine inzibacyuho na viceversa
