♠ 4 x 50 W MOSFET quad bridge power amplifier
I-TDA7850 iyisikhuthazi samandla omsindo wesigaba sobuchwepheshe be-MOSFET se-Flexiwatt 25 eklanyelwe umsakazo wemoto onamandla aphezulu. Isakhiwo sokuphumayo esihambisana ngokugcwele se-P-Channel/N-Channel sivumela ujantshi ukuba ujike ugesi ophumayo kajantshi, okuthi, kuhlanganiswe nokulahlekelwa kokuphuma okuphezulu kwamanje kanye nokuncishisiwe kokusetshenziswa kwamanzi kusethe izinkomba zamandla amasha endaweni yomsakazo wemoto, ngokusebenza okuhlanekezelwa okungenakuqhathaniswa.
I-TDA7850 ihlanganisa umtshina we-DC offset.
■ Amandla okukhipha okuphezulu:
– 4 x 50 W/4 Ω ubuningi.
– 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %
– 4 x 80 W/2 Ω ubuningi.
– 4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %
■ Isigaba samandla esiphumayo se-MOSFET
■ Ikhono elihle kakhulu lokushayela elingu-2 Ω
■ Ukuhlanekezela kwekilasi le-Hi-Fi
■ Umsindo ophumayo omncane
■ Umsebenzi we-ST-BY
