♠ 4 x 80W gelinta dhijitaalka ah fasalka-D cod-weyneeye maqal ah oo leh tayada maqalka ee Hi-Fi, ogaanshaha horumarsan, 2 MHz beddesha inta jeer iyo Bandwidth xallinta Sare
HFDA801A waa cod-weyneeye cusub oo ST class-D, gaar ahaan loogu talagalay codsiyada baabuurta ee tignoolajiyada BCD ee ugu dambeysay. HFDA801A waxay isku daraysaa 24-bits 120 dB DAC beddelaad ah, oo waxay leedahay 2 MHz beddelashada heerka PWM heerka D. Qaabayntan ayaa awood u siinaysa naqshadaynta codsi kooban oo jaban, isla markaana gaadhay heerkii ugu fiicnaa ee bandhigyada maqalka. HFDA801A waxay taageertaa codsiyada band ballaaran (80 kHz), oo leh heer aad u hooseeya ee qaylada iyo THD hooseeya. Intaa waxaa dheer, waxay soo bandhigtay jaantuska ogaanshaha ugu dhammaystiran, oo ay ku jiraan ogaanshaha buuxda ee ciyaarta si ay u taageerto shuruudaha OEM ee ugu baahida badan marka loo eego xakamaynta hadalka iyo nidaamka adkeynta / isku hallaynta. HFDA801A taageerayaashu waxay bilaabaan joojinta qulqulka ilaa 4.5 V (5 V marka la shido) waxaana lagu hayaa xirmo LQFP dhuuban oo dhuuban 10x10. Markaa HFDA801A waxay ku habboon tahay heer kasta oo codsi baabuur ah.
