♠ 4 x 80W dhijitari yekupinda kirasi-D yemotokari audio amplifier ine Hi-Fi odhiyo mhando, kuongororwa kwepamusoro, 2 MHz switching frequency uye High Resolution Bandwidth.
HFDA801A ndiyo itsva ST class-D audio amplifier, yakanyatsogadzirirwa kushandiswa kwemotokari mune yazvino BCD tekinoroji. Iyo HFDA801A inobatanidza 24-bits 120 dB DAC shanduko, uye inoratidzira 2 MHz switching PWM kirasi D yekubuda nhanho. Iyi gadziriso inogonesa dhizaini yekombuta uye isingadhure application, ichisvika panguva imwechete yakasarudzika nhanho yemitambo yekuteerera. HFDA801A inotsigira yakakura bhendi application (80 kHz), ine yakaderera zvakanyanya mwero weruzha uye yakaderera THD. Uyezve inoratidzira iyo yakazara yakazara diagnostic matrix, kusanganisira yakazara diagnostic mumutambo kutsigira zvakanyanya kudiwa zveOEM maererano nekutonga kwemutauri uye kusimba kwehurongwa / kuvimbika. HFDA801A inotsigira kutanga kumira kudzika kusvika ku4.5 V (5 V painobatidza) uye inochengeterwa mune yakanyanya compact uye yakatetepa LQFP 10x10 package. Saka iyo HFDA801A inokodzera chero nhanho yemotokari application.
• AEC-Q100 qualification iri kuenda
• Yakabatanidzwa 120 dB D/A shanduko
• I2S uye TDM madijita ekuisa (kusvika ku16 CH TDM)
• Inosarudzwa yekuisa sampuli mwero frequency (44.1/48/96/192 kHz)
• Wide supply operating range: 4.5 V - 2518 V (5 V min pakuchinja-kutendeuka)
• PWM 2 MHz kuchinja PWM:
- Yakaderedzwa saizi uye mutengo wekuburitsa LC
• High Resolution Bandwidth rutsigiro:
- Kusvika ku40 kHz (I2S 96 kHz) ine attenuation [0 dB, -2 dB]
- Kusvika ku80 kHz (I2S 192 kHz) ine attenuation [0 dB, -2 dB]
• 4 I2C kero
• 4 Ω, 2 Ω, 1 Ω kutyaira uchiburitsa nzira parallelization
• MOSFET magetsi anobuda achibvumira simba rekubuda kwepamusoro:
– Chinyorwa 4 x 30 W / 4 Ω @ 14.4 V, 1 kHz THD = 10%
– Chinyorwa 4 x 25 W / 4 Ω @ 14.4 V, 1 kHz THD = 1%
– Chinyorwa 4 x 50 W/2 Ω @ 14.4 V 1 kHz THD =10 %
– Chinyorwa 4 x 80 W/4 Ω @ 25V V, 1 kHz THD =10 %
• I2C yakazara configurability uye diagnostic:
- 4 x Yambiro yekupisa uye avhareji yekuyera tembiricha kuyerwa paI 2C (8 bits)
- AC uye DC diagnostic (yakasununguka chiteshi)
-OCP kuchengetedza chirongwa chinogadziriswa (4 x OCP muganho unosarudzwa)
- Kunyarara nguva yekugadzirisa
- DIM (digital impedance mita)
- Mhinduro mushure mekugadziriswa kwesefa
• Kugona kumhanyisa kuongororwa kwakazara mukutamba:
- Pfupi kuenda kuGND/VCC
- DC offset detector
• Ruzha rwakaderera zvakanyanya:
- 13 µV A-yakayerwa; 20 kHz (kuwedzerwa kukuru) typ
• yakaderera zvikuru THD:
- 0.02% pa1 W 1 kHz pa4 uye 2 Ω kutaipa
- 0.08% 20-20 kHz (yakazara bhendi) pa4 uye 2 Ω mitoro (1 W)
• CD/Diag pini (3 zvinosarudzwa maCD zvikumbaridzo)
• Pini yekubuditsa yekubatanidza (chete neTDM inopinza stream, paI2Sdata2)
• Channel yakazvimirira Chimumumu/ Play/Gain kusarudzwa/Diagnostic
• Real Time ikozvino monitor
• Vhura Mutoro mukutamba
• Kuraswa kwebhatiri kunoenderana (40 V)
• Immune to pop/tick ruzha pakubatidza/kudzima, kusiyanisa kwebhatiri (mukati meiyo operation range), panguva yekuongorora
• EMI kutevedza kwakaongororwa maererano neCISPR25
• Nhaka (hapana I2C mode)
• Integrated short circuit dziviriro
• ESD yakabatanidzwa dziviriro (2 kV HBM, 500 V / 750 V yekona CDM)
• LQFP64 yakafumurwa pad up package
