♠ LM4991 3W Lub Hwj Chim Lub Hwj Chim nrog Lub Hom Phiaj
Lub LM4991 yog ib qho mono-bridged audio power amplifier muaj peev xwm xa 3W ntawm lub zog nruab nrab txuas mus rau hauv 3Ω load nrog tsawg dua 10% THD thaum siv los ntawm 5V fais fab mov (saib Cov Lus Qhia hauv qab). Txhawm rau txuag hluav taws xob hauv cov ntawv thov nqa tau, LM4991's micropower shutdown hom (ISD = 0.1µA, ntaus ntawv) yog qhib thaum VDD siv rau SHUTDOWN tus pin.
Boomer audio power amplifiers yog tsim tshwj xeeb los muab lub zog siab, siab fidelity suab tso zis. Lawv xav tau ob peb cov khoom siv sab nraud thiab ua haujlwm ntawm cov khoom siv hluav taws xob tsawg los ntawm 2.2V txog 5.5V.Vim LM4991 tsis xav tau cov khoom siv hluav taws xob sib txuas, bootstrap capacitors, lossis snubber networks, nws yog qhov tsim nyog rau cov khoom siv hluav taws xob tsawg uas yuav tsum muaj qhov ntim thiab qhov hnyav.
Ntxiv LM4991 nta muaj xws li thermal shutdown tiv thaiv, kev sib koom ua ke-tau txais kev ruaj ntseg, thiab sab nrauv nce.
• Muaj nyob rau hauv Chaw-Txuag WSON thiab SOIC pob
• Ultra Low Tam sim no kaw hom
• Yuav Tsav Capacitive Loads txog 500pF
• Txhim kho Nyem thiab Pop Circuitry txo cov suab nrov thaum tig-On thiab tig-tawm kev hloov pauv
• 2.2 - 5.5V ua haujlwm
• Tsis muaj qhov tso zis coupling Capacitor, Snubber Networks, Bootstrap Capacitors lossis Gain-Setting Resistor yuav tsum tau
• Kev sib haum xeeb-tau ruaj khov
