♠ 4 x 80W zolowetsa digito za class-D audio amplifier zomvera zamtundu wa Hi-Fi, zowunikira zapamwamba, 2 MHz switch frequency and High Resolution Bandwidth
HFDA801A ndi ST class-D audio amplifier yatsopano, yopangidwa makamaka kuti igwiritsidwe ntchito pamagalimoto muukadaulo waposachedwa wa BCD.HFDA801A imaphatikiza kutembenuka kwa 24-bits 120 dB DAC, ndipo imakhala ndi 2 MHz switching PWM class D gawo lotulutsa.Kukonzekera uku kumathandizira kupanga pulogalamu yocheperako komanso yotsika mtengo, yomwe imafikira nthawi yomweyo mulingo wapamwamba wamawu.HFDA801A imathandizira ma bandi ambiri (80 kHz), okhala ndi phokoso lotsika kwambiri komanso THD yotsika.Komanso imakhala ndi matrix ozindikira bwino kwambiri, kuphatikiza kuzindikira kwathunthu pamasewera kuti athandizire zofunika kwambiri za OEM potengera kuwongolera kwa olankhula komanso kulimba kwadongosolo / kudalirika.HFDA801A imathandizira kuyamba kuyimitsa kutsika mpaka 4.5 V (5 V poyatsa) ndipo imayikidwa mu phukusi laling'ono komanso lopyapyala la LQFP 10x10.Chifukwa chake HFDA801A ndiyoyenera pamlingo uliwonse wamagalimoto.
• Chiyeneretso cha AEC-Q100 chikupita
• Integrated 120 dB D/A kutembenuka
• I2S ndi TDM zolowetsa digito (mpaka 16 CH TDM)
• Zitsanzo zosinthira pafupipafupi (44.1/48/96/192 kHz)
• Kuchuluka kwa magwiridwe antchito: 4.5 V - 2518 V (5 V min pakusintha koyatsa)
• PWM 2 MHz kusintha PWM:
- Kuchepetsa kukula ndi mtengo wa linanena bungwe LC
• Chithandizo cha High Resolution Bandwidth:
- Kufikira 40 kHz (I2S 96 kHz) yokhala ndi attenuation [0 dB, -2 dB]
- Kufikira 80 kHz (I2S 192 kHz) yokhala ndi attenuation [0 dB, -2 dB]
• Maadiresi a 4 I2C
• 4 Ω, 2 Ω, 1 Ω kuyendetsa ndi njira zotulutsa zofanana
• Zotulutsa zamagetsi za MOSFET zomwe zimalola kuti pakhale mphamvu zambiri:
- Lembani 4 x 30 W / 4 Ω @ 14.4 V, 1 kHz THD = 10%
- Mtundu 4 x 25 W / 4 Ω @ 14.4 V, 1 kHz THD = 1%
- Lembani 4 x 50 W/2 Ω @ 14.4 V 1 kHz THD =10 %
- Lembani 4 x 80 W/4 Ω @ 25V V, 1 kHz THD =10 %
• I2C kusinthika kwathunthu ndi matenda:
- Chenjezo la 4 x ndi kutentha kwapakati pa I 2C (8 bits)
- Kuzindikira kwa AC ndi DC (kopanda njira)
- Chiwembu chachitetezo cha OCP chosinthika (4 x OCP malire osankhidwa)
- Sinthani nthawi yolankhula
- DIM (digito ya impedance mita)
- Ndemanga pambuyo kasinthidwe fyuluta
• Kutha kuyendetsa matenda athunthu mumasewera:
- Mwachidule mpaka GND/VCC
- Chowunikira cha DC
• Phokoso Lapansi Kwambiri:
- 13 µV A-yolemetsa;20 kHz (kupindula kwakukulu) mtundu
• THD yotsika kwambiri:
- 0.02% pa 1 W 1 kHz pa 4 ndi 2 Ω polemba katundu
- 0.08% 20-20 kHz (gulu lathunthu la audio) pa 4 ndi 2 Ω katundu (1 W)
• CD/Diag pini (ma CD 3 osasankhidwa)
• Pini yotulutsa yolumikizana (yokha ndi makina olowetsa a TDM, pa I2Sdata2)
• Njira yodziyimira payokha Musalankhule/Sewerani/Gain kusankha/Diagnostic
• Real Time panopa polojekiti
• Tsegulani Katundu mu sewero
• Kutaya kwa batri kumagwirizana (40 V)
• Phokoso la chitetezo champhamvu pakuyatsa / kuzimitsa, kusintha kwa batri (mkati mwa opareshoni), panthawi yozindikira
• Kutsata kwa EMI koyesedwa molingana ndi CISPR25
• Cholowa (palibe I2C mode)
• Integrated short circuit chitetezo
• Chitetezo chophatikizika cha ESD (2 kV HBM, 500 V / 750 V ngodya CDM)
