♠ 4 x 80W oni-nọmba igbewọle kilasi-D ampilifaya ohun afetigbọ pẹlu didara ohun afetigbọ Hi-Fi, awọn iwadii ilọsiwaju, igbohunsafẹfẹ iyipada 2 MHz ati bandiwidi Iwọn giga
HFDA801A jẹ ampilifaya ohun afetigbọ kilasi-D tuntun ST, apẹrẹ pataki fun awọn ohun elo adaṣe ni imọ-ẹrọ BCD tuntun. HFDA801A ṣepọ 24-bits 120 dB DAC iyipada, ati awọn ẹya 2 MHz yiyi PWM kilasi D ipele o wu. Iṣeto ni yii ngbanilaaye apẹrẹ ti iwapọ ati ohun elo ilamẹjọ, de ni akoko kanna ipele ti o tayọ ti awọn iṣe ohun. HFDA801A ṣe atilẹyin awọn ohun elo igbohunsafefe jakejado (80 kHz), pẹlu ariwo kekere pupọ ati THD kekere.
