♠ LM4991 3W Audio Power Amplifier yokhala ndi Shutdown Mode
LM4991 ndi mono bridged audio amplifier power amplifier yomwe imatha kupereka 3W yamphamvu yopitilira muyeso wa 3Ω wokhala ndi zosakwana 10% THD poyendetsedwa ndi magetsi a 5V (onani Zolemba pansipa). Kuti musunge mphamvu pamapulogalamu osunthika, LM4991's micropower shutdown mode (ISD = 0.1µA,typ) imayatsidwa VDD ikayikidwa pa SHUTDOWN pini.
Ma audio amplifiers a Boomer adapangidwa makamaka kuti apereke mphamvu zambiri, zotulutsa zomvera kwambiri. Amafuna zigawo zochepa zakunja ndikugwira ntchito pamagetsi otsika kuchokera ku 2.2V mpaka 5.5V.Popeza LM4991 sichifuna ma capacitor ophatikizana otulutsa, bootstrap capacitors, kapena ma snubber networks, ndiyoyenererana ndi machitidwe otsika amphamvu omwe amafunikira mphamvu zochepa komanso kulemera kwake.
Zowonjezera za LM4991 zikuphatikiza chitetezo chotseka, kukhazikika kwa mgwirizano, komanso kukhazikitsidwa kwakunja.
