♠ 4 x 80W kikohoʻe hoʻokomo kikohoʻe papa-D automotive leo amplifier me ka Hi-Fi leo maikaʻi, holomua diagnostics, 2 MHz hoʻololi pinepine a me High Resolution Bandwidth

ʻO HFDA801A ka mea hoʻonui leo ST class-D hou, i hoʻolālā ʻia no nā noi kaʻa i ka ʻenehana BCD hou loa.Hoʻohui ka HFDA801A i kahi hoʻololi 24-bits 120 dB DAC, a me nā hiʻohiʻona 2 MHz e hoʻololi ana i ka pae puka PWM papa D.Hāʻawi kēia hoʻonohonoho i ka hoʻolālā ʻana o kahi noi paʻa a maʻalahi hoʻi, hiki i ka manawa like ke kūlana kiʻekiʻe o nā hana leo.Kākoʻo ʻo HFDA801A i nā noi band ākea (80 kHz), me ka haʻahaʻa haʻahaʻa o ka walaʻau a me ka THD haʻahaʻa.Eia kekahi, hōʻike ia i ka matrix diagnostic piha loa, me ka diagnostic piha i ka pāʻani e kākoʻo i nā koi OEM koi nui e pili ana i ka mana leo ʻōlelo a me ka ʻōnaehana ikaika / hilinaʻi.Kākoʻo ʻo HFDA801A e hoʻomaka i ka hoʻōki ʻana a hiki i ka 4.5 V (5 V i ka hoʻomaka ʻana) a waiho ʻia i loko o kahi pūʻolo LQFP 10x10 ʻoi loa a lahilahi.No laila ua kūpono ka HFDA801A no kēlā me kēia pae o ka noi automotive.
