♠ 4 x 80W digital input class-D automotive audio amplifier with Hi-Fi audio quality, advanced diagnostics, 2 MHz switching zaus thiab High Resolution Bandwidth
HFDA801A yog tus tshiab ST chav kawm-D suab amplifier, tsim tshwj xeeb rau kev siv tsheb hauv BCD thev naus laus zis tshiab. HFDA801A integrates 24-ntsis 120 dB DAC hloov dua siab tshiab, thiab nta 2 MHz hloov PWM chav kawm D tso zis theem. Qhov kev teeb tsa no ua rau tus tsim ntawm daim ntawv thov compact thiab pheej yig, ncav cuag tib lub sijhawm zoo ntawm kev ua yeeb yam suab. HFDA801A txhawb nqa cov ntawv thov dav dav (80 kHz), nrog cov suab nrov qis thiab qis THD. Tsis tas li ntawd nws nta cov kev kuaj mob ua tiav tag nrho, suav nrog kev kuaj mob tag nrho hauv kev ua si los txhawb cov kev xav tau OEM tshaj plaws nyob rau hauv cov nqe lus ntawm kev hais lus tswj thiab qhov system robustness / kev ntseeg siab. HFDA801A txhawb nqa pib nres cranking mus rau 4.5 V (5 V thaum tig rau) thiab nws yog nyob rau hauv ib tug heev compact thiab nyias LQFP 10x10 pob. Yog li HFDA801A yog qhov tsim nyog rau txhua qib ntawm daim ntawv thov tsheb.
