♠ Kugwiritsa ntchito bwino kwambiri kwa digito pamagalimoto amagetsi a quad okhala ndi zida zowunikira, 'kuyamba kuyimitsa' kumagwirizana
TDA7803A ndi single chip quad bridge amplifier muukadaulo wapamwamba wa BCD kuphatikiza: chosinthira chathunthu cha D/A, kuyika kwa digito kuti mulumikizidwe molunjika ku I2S (kapena TDM) ndi magawo amphamvu otulutsa a MOSFET.
Chosinthira cha D/A chophatikizika chimalola magwiridwe antchito kuti afike pamlingo wapamwamba kwambiri wa 115 dB S/N ndi zopitilira 110 dB zamitundu yosiyanasiyana.
Kuphatikiza apo, TDA7803A imaphatikiza lingaliro laukadaulo lapamwamba, lokonzedwanso ndi ma siginecha osagwirizana.Chipangizochi chapangidwa kuti chizigwirizana ndi kusintha kwa batri pamakina a class-G.
Chifukwa cha lingaliro ili, "mphamvu yotulutsa" yotayidwa pansi pamikhalidwe yomvera imatha kuchepetsedwa mpaka 50% poyerekeza ndi mayankho anthawi zonse a AB.
TDA7803A imaphatikizanso PLL yosinthika yomwe imatha kutseka ma frequency a 64 * Fs pazosintha zonse.
Chipangizocho chili ndi mndandanda wathunthu wowunikira zomwe zimalankhula za wokamba aliyense kudzera pa basi ya I2C.Basi yomweyo ya I2C imalola kuwongolera masanjidwe angapo a chipangizocho.
TDA7803A imatha kuyimba nyimbo mpaka 6 V magetsi operekera - kotero imagwirizana ndi zomwe zimatchedwa 'start stop' mbiri ya batri yomwe yatengedwa posachedwa ndi opanga magalimoto angapo (potero amachepetsa kuwononga mafuta komanso kukhudzidwa kwa chilengedwe).
AEC-Q100 oyenerera
· 24-bit digito processing
· 115 dB dynamic range (A-yolemetsa)
· SB-I (SB - bwino) yogwira ntchito bwino kwambiri 'non - class D' bwino kwambiri
· Parallel mode ntchito kupezeka
· Kuthekera kwakukulu kwamphamvu:
- 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:
- Mabasi athunthu a I2C oyendetsa 1.8V/3.3V) okhala ndi ma adilesi anayi osankhidwa (pokhapokha pa PowerSO36 phukusi)
- Kuyimilira kutsogolo / kusewera kumbuyo / osalankhula
- Zopindulitsa za digito zomwe zingasankhidwe pakuchita phokoso lotsika kwambiri
- Digital diagnostics ndi DC ndi AC katundu kuzindikira
Kugwirizana koyambira (kutsika mpaka 6V)
* Mitengo yazitsanzo: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz
- Flexible serial data port (1.8 V / 3.3 V):- I2S standard, TDM 4Ch, TDM 8Ch, TDM 16ch (8+8ch)
· Chowunikira cha Offset
· Chojambulira chodziyimira pawokha kutsogolo / kumbuyo
· Programmable diagnostic pini
· Pini yolumikizira yogwirizana ndi CMOS
· Chitetezo chamafuta
· Pop yaulere osalankhula kusewera masinthidwe ndi viceversa
