♠ 4 x 50 W MOSFET quad alalaupapa fa'amalosi malosi
O le TDA7850 o se fa'auluuluga fa'atekonolosi a le MOSFET vasega AB fa'amalosi leo i le pusa Flexiwatt 25 ua fa'atulagaina mo le leitio ta'avale maualuga. O le atoatoa atoatoa P-Channel / N-Channel fausaga galuega faatino e mafai ai se nofoaafi i nofoaafi galuega faatino swing lea, tu'ufa'atasi ma le maualuga o le gaosiga o lo'o i ai nei ma fa'aititia le gau saturation seti fa'amatalaga mana fou i totonu o le fanua ta'avale-leitio, fa'atasi ai ma fa'atinoga fa'aletonu le mafaatusalia.
O le TDA7850 o loʻo tuʻufaʻatasia se DC offset detector.
■ Malosiaga maualuga e mafai ona gaosia:
– 4 x 50 W/4 Ω maualuga.
– 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %
– 4 x 80 W/2 Ω maualuga.
– 4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %
■ MOSFET tulaga o le malosiaga o le gaosiga
■ Lelei 2 Ω le mafai ona ave taavale
■ Fa'aletonu vasega Hi-Fi
■ Le pisapisao maualalo
■ galuega ST-BY
■ Faalogo leo
■ Otometi ile min. su'esu'e voltage
■ E maualalo le aofa'i o vaega i fafo:
– Fa'amaumau fa'asili (26 dB)
- Leai se taui mai fafo
- Leai ni capacitors bootstrap
■ I luga o le vaa 0.35 O se avetaavale pito maualuga
■ Tuuina atu le ala pupuu i gnd, i Vs, i luga o le uta
■ O uta fa'aosoina tele
■ Ova le vevela vevela ma le fa'agata fa'amama vaivai
■ Output DC offset su'esu'ega
■ Tu'u i luga le eletise lafoa'i
■ Gnd tatala avanoa
■Maa fa'aliliu
