♠ 4 x 50 W MOSFET quad bridge power amplifier
I-TDA7850 iyisikhuthazi samandla omsindo wekilasi lobuchwepheshe le-MOSFET AB kuphakheji ye-Flexiwatt 25 eklanyelwe umsakazo wemoto onamandla aphezulu.Isakhiwo sokuphuma kwe-P-Channel/N-Channel esihambisana ngokugcwele sivumela ujantshi ukuba ujike ugesi ophumayo kajantshi, okuthi, kuhlanganiswe nokulahlekelwa okuphumayo okuphezulu kwamanje kanye nokuncishisiwe kokugcwala 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
■ Thulisa umsebenzi
■ Thulisa kancane.ukutholakala kwe-voltage
■ Isibalo esiphansi sengxenye yangaphandle:
- Inzuzo engaguquki yangaphakathi (26 dB)
- Ayikho isinxephezelo sangaphandle
- Awekho ama-capacitor we-bootstrap
■ Ebhodini 0.35 Umshayeli oseceleni okuphezulu
■ Khipha isekethe emfushane ukuya ku-gnd, ukuya ku-Vs, ngaphesheya komthwalo
■ Imithwalo eguquguqukayo kakhulu
■ Ukushisa kwe-chip ngokwedlulele ngesikhawuli esithambile esishisayo
■ Ukutholwa kwe-offset ye-DC okukhiphayo
■ Layisha i-voltage yokulahla
■ Fortuitous open gnd
