♠ 4 x 80W na'urar shigar dijital ta aji-D amplifier audio na mota tare da ingancin sauti na Hi-Fi, bincike na ci gaba, mitar sauyawa 2 MHz da Bandwidth High Resolution.
HFDA801A shine sabon ST class-D amplifier audio, wanda aka tsara musamman don aikace-aikacen mota a sabuwar fasahar BCD. HFDA801A yana haɗa 24-bits 120 dB DAC juzu'i, kuma yana fasalta 2 MHz mai sauyawa matakin fitowar PWM aji D. Wannan tsarin yana ba da damar ƙirƙira ƙaƙƙarfan aikace-aikace mara tsada, yana kaiwa a lokaci guda fitaccen matakin wasan kwaikwayo na sauti. HFDA801A tana goyan bayan aikace-aikacen bandeji mai faɗi (80 kHz), tare da ƙaramin ƙaramar amo da ƙaramin THD. Hakanan yana fasalta mafi kyawun matrix na bincike, gami da cikakken bincike a cikin wasa don tallafawa mafi yawan buƙatun OEM dangane da sarrafa lasifika da ƙarfin tsarin / aminci. HFDA801A yana goyan bayan fara dakatar da karkacewa zuwa 4.5 V (5V a kunna) kuma ana ajiye shi a cikin ƙaramin kunshin LQFP 10 × 10 na bakin ciki. Don haka HFDA801A ya dace da kowane matakin aikace-aikacen mota.
