HFDA801A nuburyo bushya bwa ST class-D amajwi yongerera amajwi, yagenewe byumwihariko porogaramu zikoresha amamodoka muburyo bwa tekinoroji ya BCD.HFDA801A ihuza 24-bits 120 dB DAC ihinduka, ikanagaragaza 2 MHz ihindura PWM icyiciro D gisohoka.Iboneza rituma igishushanyo mbonera cyoroshye kandi kidahenze, kigera icyarimwe urwego rwiza rwibikorwa byamajwi.HFDA801A ishyigikira umurongo mugari wa porogaramu (80 kHz), hamwe nurwego rwo hasi cyane rwurusaku na THD nkeya.Byongeye kandi iragaragaza matrike yuzuye yo kwisuzumisha, harimo kwisuzumisha ryuzuye mugukina kugirango ishyigikire ibisabwa OEM isabwa cyane mubijyanye no kugenzura imvugo no gukomera kwa sisitemu.HFDA801A ishyigikira gutangira guhagarara kugeza kuri 4.5 V (5 V ifunguye) kandi ibitse mububiko bworoshye kandi bworoshye LQFP 10x10.Rero HFDA801A irakwiriye kurwego urwo arirwo rwose rwo gukoresha imodoka.
• Impamyabumenyi ya AEC-Q100 igenda
• Kwinjiza 120 dB D / Guhindura
• I2S na TDM byinjijwe muburyo bwa digitale (kugeza kuri 16 CH TDM)
• Guhitamo ibyitegererezo byerekana urugero inshuro (44.1 / 48/96/192 KHz)
• Ibikorwa byinshi byo gutanga: 4.5 V - 2518 V (5 V min mugihe cyo gufungura)
• PWM 2 MHz ihindura PWM:
- Kugabanya ingano nigiciro cyibisohoka LC
• Inkunga ihanitse yumurongo mugari:
- Kugera kuri 40 KHz (I2S 96 kHz) hamwe na attenuation [0 dB, -2 dB]
- Kugera kuri 80 kHz (I2S 192 kHz) hamwe na attenuation [0 dB, -2 dB]
• 4 I2C aderesi
• 4 Ω, 2 Ω, 1 Ω gutwara hamwe numuyoboro usohoka ugereranije
• MOSFET yingufu zisohoka zitanga ingufu zisohoka cyane:
- Andika 4 x 30 W / 4 Ω @ 14.4 V, 1 kHz THD = 10%
- Andika 4 x 25 W / 4 Ω @ 14.4 V, 1 kHz THD = 1%
- Andika 4 x 50 W / 2 Ω @ 14.4 V 1 kHz THD = 10%
- Andika 4 x 80 W / 4 Ω @ 25V V, 1 kHz THD = 10%
• I2C yuzuye kandi isuzumwa:
- 4 x Imenyesha ryubushyuhe hamwe nimpuzandengo yubushyuhe bwo gupima kuri I 2C (8 bits)
- Gusuzuma AC na DC (bitagendeye kumuyoboro)
- Gahunda yo gukingira OCP igaragara (4 x OCP ntarengwa ishobora guhitamo)
- Gucecekesha igihe
- DIM (metero ya impedance ya metero)
- Ibisubizo nyuma yo gushungura
• Ubushobozi bwo gukora isuzumabumenyi ryuzuye mukina:
- Bigufi kuri GND / VCC
- Detset ya DC
• Urusaku ruke cyane:
- 13 µV A-uburemere;20 kHz (inyungu nyinshi) ubwoko
• THD iri hasi cyane:
- 0,02% kuri 1 W 1 kHz kuri 4 na 2 Ω imitwaro yandika
- 0.08% 20-20 kHz (bande yuzuye amajwi) kuri 4 na 2 Ω imizigo (1 W)
• CD / Diag pin (3 yatoranijwe ya CD)
• Guhuza ibisohoka pin (gusa hamwe na TDM yinjiza, kuri I2Sdata2)
• Umuyoboro wigenga Mute / Gukina / Kunguka guhitamo / Gusuzuma
• Ikurikiranabikorwa ryigihe
• Fungura umutwaro mukina
• Gutwara imizigo ya bateri ihuza (40 V)
• Irinde urusaku rwa pop / tick igihe uzimye / kuzimya, guhinduranya bateri (imbere mubikorwa bikora), mugihe cyo kwisuzumisha
• kubahiriza EMI byasuzumwe hakurikijwe CISPR25
• Umurage (nta buryo bwa I2C)
• Kurinda imiyoboro migufi irinzwe
• ESD ikingira ikingira (2 kV HBM, 500 V / 750 V imfuruka CDM)
• LQFP64 yashyizwe ahagaragara pack up
