♠ 4 x 80W te karaehe whakauru mamati-D te whakakaha ororongo miihini me te kounga ororongo Hi-Fi, nga tātaritanga matatau, te 2 MHz te huringa whakawhiti me te Aratuku Whakatau Teitei
Ko te HFDA801A te whakakaha ororongo ST akomanga-D hou, i hangaia mo nga tono miihini i roto i nga hangarau BCD hou. Ko te HFDA801A e whakauru ana i te huringa 24-bits 120 dB DAC, me te whakaatu i te 2 MHz whakawhiti PWM akomanga D te wahanga putanga. Ma tenei whirihoranga ka taea te hoahoa o te tono kiato me te utu iti, ka eke ki te taumata oro oro. E tautoko ana a HFDA801A i nga tono roopu whanui (80 kHz), he iti rawa te haruru me te THD iti. I tua atu, kei te whakaatu i te matrix tātaritanga tino oti, tae atu ki te tātaritanga katoa i roto i te taakaro hei tautoko i nga whakaritenga OEM tino nui mo te mana orooro me te pakari o te punaha / pono. Ko nga tautoko HFDA801A ka tiimata ka mutu ki te 4.5 V (5 V i te wa e ka ana) ka noho ki roto i te kete LQFP 10x10 tino kiato me te kikokore. No reira he pai te HFDA801A mo tetahi taumata o te tono miihini.
