♠ LM4991 3W Audio Power Amplifier me ke ʻano pani
ʻO ka LM4991 kahi mono bridged power amplifier hiki ke hāʻawi i ka 3W o ka mana awelika mau i loko o kahi ukana 3Ω me ka liʻiliʻi o 10% THD ke hoʻohana ʻia e kahi lako mana 5V (e ʻike i ka Nānā ma lalo). No ka mālama ʻana i ka mana ma nā polokalamu kelepona, hoʻāla ʻia ke ʻano hoʻopaʻa micropower o LM4991 (ISD = 0.1µA, typ) ke hoʻohana ʻia ʻo VDD i ka pine SHUTDOWN.
Hoʻolālā kikoʻī ʻia nā mea hoʻonui leo leo Boomer e hāʻawi i ka mana kiʻekiʻe, kiʻekiʻe ʻoiaʻiʻo. Pono lākou i ka liʻiliʻi o nā ʻāpana o waho a hana i nā volta haʻahaʻa haʻahaʻa mai 2.2V a i 5.5V. No ka mea ʻaʻole koi ka LM4991 i nā capacitors hoʻopili hoʻopuka, nā capacitor bootstrap, a i ʻole nā pūnaewele snubber, kūpono ia no nā ʻōnaehana haʻahaʻa haʻahaʻa e koi ana i ka liʻiliʻi liʻiliʻi a me ke kaumaha.
ʻO nā hiʻohiʻona LM4991 hou e pili ana i ka pale pani pani wela, unity-gain stability, a me ka loaʻa ʻana o waho.
• Loaʻa i loko o nā Pūʻulu WSON a me SOIC
• Ke ʻano hoʻopaʻa haʻahaʻa haʻahaʻa loa
• Hiki ke hookele i na haawe Capacitive a hiki i 500pF
• Hoʻemi ʻia ka Piʻi a me ka Pop Circuitry i nā walaʻau i ka wā o ka hoʻohuli ʻana a me ka hoʻopau ʻana.
• 2.2 - 5.5V hana
• ʻAʻohe mea hoʻohui i nā mea hoʻopili, nā Snubber Networks, Bootstrap Capacitors a i ʻole nā Resistor hoʻonohonoho Gain-Setting e koi ʻia.
• Unity-Gain Stable
