♠ 4 x 80W dijithale tse kenyelletsoang sehlopha-D amplifier ea molumo oa molumo oa Hi-Fi, tlhahlobo e tsoetseng pele, 2 MHz switch frequency le High Resolution Bandwidth
HFDA801A ke sebuela-hōle se secha sa ST class-D, se etselitsoeng ka ho khetheha lisebelisoa tsa likoloi ho theknoloji ea morao-rao ea BCD. HFDA801A e kopanya phetoho ea 24-bits 120 dB DAC, 'me e na le 2 MHz switching PWM class D sethaleng. Tokiso ena e etsa hore ho be le moralo oa ts'ebeliso e kopaneng le e theko e tlase, e fihlelang ka nako e ts'oanang boemo bo hlahelletseng ba molumo oa molumo. HFDA801A e ts'ehetsa lits'ebetso tsa sehlopha se pharaletseng (80 kHz), e nang le lerata le tlase haholo le THD e tlase. Ho feta moo e na le matrix a tlhahlobo e felletseng ka ho fetesisa, ho kenyelletsa tlhahlobo e felletseng ea papali ho ts'ehetsa litlhoko tse batloang haholo tsa OEM ho latela taolo ea sebui le ho tiea ha sistimi / ts'epahalo. HFDA801A e ts'ehetsa ho qala ho emisa ho theoha ho 4.5 V (5 V ha e buletsoe) 'me e behiloe ka har'a sephutheloana se thata haholo sa LQFP 10x10. Kahoo HFDA801A e loketse boemo bofe kapa bofe ba ts'ebeliso ea likoloi.
