♠ LM4991 3W Amajwi Amplifier hamwe na Shutdown Mode
LM4991 ni mono ikiraro cyamajwi yongerera imbaraga ubushobozi bwo gutanga 3W yingufu zingana zingana mumutwaro wa 3Ω ufite munsi ya 10% THD mugihe ikoreshwa numuriro wa 5V (reba Icyitonderwa hepfo). Kugirango ubungabunge imbaraga mubisabwa byoroshye, uburyo bwa LM4991 bwo guhagarika amashanyarazi (ISD = 0.1µA, andika) burakora mugihe VDD ikoreshwa kuri pin ya SHUTDOWN.
Boomer amajwi yingufu zamajwi zateguwe byumwihariko kugirango zitange imbaraga nyinshi, amajwi menshi yo kwizerwa. Bakenera ibice bike byo hanze kandi bigakorera kumashanyarazi make kuva kuri 2.2V kugeza 5.5V.Kubera ko LM4991 idakenera ubushobozi bwo gusohora ibintu, ubushobozi bwa bootstrap, cyangwa imiyoboro ya snubber, birakwiriye rwose kuri sisitemu ntoya ishobora gutwara ibintu bisaba ubunini nuburemere.
Ibindi byongeweho LM4991 harimo kurinda ubushyuhe bwo guhagarika ubushyuhe, ubumwe-bwunguka umutekano, hamwe ninyungu zashizweho.
• Iraboneka mumwanya-uzigama WSON hamwe na SOIC
• Ultra Ntoya yo Guhagarika Uburyo
• Irashobora gutwara imizigo ifite ubushobozi bugera kuri 500pF
• Kunoza Kanda na Pop Inzira Zigabanya Urusaku Mugihe cyo gufungura no kuzimya
