TDA7803A jẹ ampilifaya afara quad chirún kan ni iṣọpọ imọ-ẹrọ BCD to ti ni ilọsiwaju: oluyipada D/A ni kikun, igbewọle oni-nọmba fun asopọ taara si I2S (tabi TDM) ati awọn ipele iṣelọpọ MOSFET ti o lagbara.
Oluyipada D/A ti irẹpọ gba iṣẹ laaye lati de ipin 115 dB S/N to dayato pẹlu diẹ sii ju 110 dB ti iwọn agbara.
Jubẹlọ TDA7803A integrates ohun aseyori ga ṣiṣe Erongba, iṣapeye tun fun aiṣedeede orin awọn ifihan agbara. A ṣe apẹrẹ ẹrọ naa lati wa ni ibamu si awose batiri fun awọn ọna ṣiṣe-G.
